Wireless high-frequency antennas next to infants - is it a good idea?

Infant intercom devices (baby monitors) consist of a transmitter and a receiver or two transceivers that constantly emit high-frequency radiation (wireless).

Some scientists argue that children's exposure to elevated levels of electromagnetic radiation can result in incomplete or problematic development of the brain and is possibly associated with the significant and continuous increase in the percentage of children who have hyperactivity, attention deficit, pervasive developmental disorder or autistic spectrum disorders (autism, etc.), aggression, psychological problems etc.

There has been a 60-fold increase in ASD in recent years, which cannot be accounted for by improvements in diagnostic methods and can only be explained by changes in the environment. This increase corresponds in time to the proliferation of mobile telecommunications, Wi-Fi, and microwave ovens as well as extremely low frequency fields from household wiring and domestic appliances. We can now explain at least some of this in terms of electromagnetically-induced membrane leakage leading to brain hyperactivity and abnormal brain development. Dr. Andrew Goldsworthy, former lecturer Imperial College London [1]

Is there is a baby monitor with low radiation?

In most countries the permissible by law safe limits of exposure to high frequency radiation are so high, that even if your baby wears a hat with a wi-fi antenna on his head all day it would be considered safe.

In recent years many scientific bodies have proposed new safe exposure limits (<100mW / m2) to protect the public from artificial electromagnetic fields, based on new studies showing that even low, non-thermal, radiation levels can lead to serious health effects. These limits are exceeded in most cases when there is a baby monitor in the same room.

It is unlikely that there is a wireless baby monitor with minimal radiation emissions, because very low transmission power would make the baby monitor work only for a very small distance.

Did you know that baby monitors antennas can expose your child to more radiation than a neighboring cell phone mast? This is because baby monitors, although they have lower power than cell phone masts are located indoors and in very shorter distances. You can easily measure the radiation from your baby monitor or other wireless radiation sources with a simple to use high-frequency radiation meter.

"Because there are suggestions that RF exposure may be more hazardous for the fetus and child due to their greater susceptibility, prudent avoidance is one approach to keeping children’s exposure as low as possible." World Health Organization [2]

Possible effects on children's development

Wireless radiation emitted by baby monitors, mobile and cordless phones, wireless modems (Wi-Fi) etc.:

  • inhibit the formation of abnormal electromagnetic activity of the brain, which is stabilized at around age 12, which explains the increasing incidence of hyperactivity and epilepsy in children ages according to Dr. Gerard Hyland, biophysicist at Warwick University and 2 times nominated for the Nobel Prize of Medicine [3]
  • cause the creation of many random and useless neural connections, which explains the usually larger skull of autistic children, according to Dr. Andrew Goldsworthy, former assistant of Imperial College London [4]
  • Detunes the initial calibration of the brain networks and the mirror-neuron system in newborns, leading to autistic behavior patterns (Thornton [5]) and are a possible cause of the contemporary increase in cases of autism (Kane [6])

"The adverse effects of electrosmog may take decades to be appreciated, although some, like carcinogenicity, are already starting to surface. This gigantic experiment on our children and grandchildren could result in massive damage to mind and body with the potential to produce a disaster of unprecedented proportions, unless proper precautions are immediately implemented." Paul Rosch, professor of medicine at New York Medical School [7]

Why are infants are more vulnerable to electromagnetic radiation?

  • their immune system is less developed than that of adults
  • the increased proliferation of infant cells makes them more vulnerable to genetic damage [8]
  • the biological effects on cell growth caused by exposure to artificial radiation are much greater in young and rapidly growing cells than in adult ones (Kwee 2003 [9] )
  • the penetration of the radiation is deeper in minors because of their smaller brain size, the thinner bone and larger water capacity (increased conductivity).

Interception of wireless signal

The interception of audio and video from wireless baby monitors has gotten much larger dimensions than you might think in recent years.

Despite assurances to the contrary by some manufacturers, the signal from the baby monitor can be intercepted.

Moreover, in recent years, live images from baby monitor cameras are intercepted and broadcasted live online.

Digital or analog baby monitor?

The analog type baby monitors broadcast in frequencies 40-900MHz and usually have lower radiation emissions than the digital ones. They are also more economic, however they are considered more vulnerable to interference and eavesdropping.

Digital broadcasting baby monitors (usually DECT) transmit at frequencies 1800-2400MHz, are often encrypted to prevent interception of the signal, but many claim this is sufficient to avoid signal interception. They are aslo vulnerable to interference when placed near other microwave sources (eg cordless phones and wi-fi modems).

Moreover, the digital baby monitors typically have higher emissions than the analog type. In addition, the digital-pulse waveform is considered by many scientists biologically more burdensome than the analog sinusoidal waveform.

Bioinitiative Report (report by international team of scientists who summed up data from more than 2000 studies on the effects of artificial electromagnetic fields) concludes that:

"There is substantial scientific evidence that some modulated fields (pulsed or repeated signals) are bioactive, which increases the likelihood that they could have health impacts with chronic exposure even at very low exposure levels. Modulation signals may interfere with normal, non-linear biological processes. Modulation is a fundamental factor that should be taken into account in new public safety standards; at present it is not even a contributing factor." [11]

Safer alternatives - Wired intercom

Good alternative to wireless devices are wired intercom systems which are connected via cable or the existing electric circuits of the apartment.

There is also the option of wired surveillance cameras. These systems, include cameras and small screen, giving you the ability to have visual and auditory contact with your child's room.

Is intercom really necessary?

It is rather surprising how he managed to survive as humans without baby monitors until today.

As the pediatrician and author Claudia Gold says baby monitors abuse parents vulnerability for profit [12], as they are not a necessity, except for some specific cases where the child has a medical condition for which continued monitoring is recommended.

Prevention of sudden infant death syndrome?

Although advertised as a major benefit of baby monitors, there is no evidence that they help prevent sudden infant death syndrome [13].

In contrast, many doctors believe that baby monitors give parents a false sense of security [14].

Infant choking

The US Consumer Product Safety Commission (CPSC) warns parents that the wires of baby monitors (wired or wireless ones) pose a risk for choking the infant when placed very near the cribs.

In the USA Since 2002, seven infants have been strangled by baby monitor cords [15].

Less actual care

Baby monitoring can reduce the time parents actually deal with the baby themselves.

More anxious parents

Parents are more anxious and wake up more often than necessary, especially if the baby monitor gives frequent false alarms.

Development of negative sleep patterns

The immediate response of the parents to each sound of the baby monitor, according to some research negatively affects the sleeping patterns of babies, by not letting them learn how to calm themsleves. [16]

If you insist on buying a wireless baby monitor ..

  • Prefer analog type rather than digital type.
  • Avoid baby monitors with bidirectional communication by which a parent can talk with the child, because these will have elevated radiation emissions from both parents and baby units.
  • Avoid baby monitor with lots of lights - affect nighttime melatonin production - safer light color red.
  • Move the baby monitor as far as possible (at least 2 meters away) from the child's crip.
  • Buy a high-frequency radiation meter to record the radiation in the children's bedroom from the baby monitor and other sources of electromagnetic radiation so you avoid placing the cot in the most burdened areas.

Wireless baby monitors, in our opinion, may be the most dangerous source of radiation today, since the development of the nervous system occurs only once in every person's life and the possible harm to infant brain is irreversible.

Cell phone radiation? Does it cause cancer? How to reduce your exposure

For the first time in history, most of the human population places a wireless radiation antenna next to his head for minutes to hours a day. Are there are health effects from cell phone use? Does it cause cancer? Why is it associated with infertility? What should children and pregnant women be aware of? Are the various products for mobile radiation protection working? Does it help to use Bluetooth; What is SAR; When does the mobile emits 28 times more radiation? Are there are effective ways to protection from cell phone radiation?


cellmobilephoneradiation

What kind of radiation is emitted?

Your mobile phone emits non ionizing pulsed radio frequency radiation 900-2100MHz while talking.

When you are not speaking to the phone (in stand by mode), the mobile phone transmits only intermittently to communicate with the nearest mobile antenna, but continuously transmits if you have enabled the Wi-Fi antenna and / or data antenna for downloading data from the Internet.

Are there are health effects?

The World Health Organization (WHO) has included cell phone radiation to the list of possible carcinogens based on research which links mobile phones with brain cancer.

Heavy use of mobile phones can cause long term health problems.

  • Using a mobile phone destroys nerve cells according to universities in Frankfurt, in Bristol, in Verona, Florence and others [1]
  • Less than a minute of talking to the cell phone is enough to cause the accumulation of red blood cells
  • Damage to DNA, leukemia and cancer have been recorded by universities in the USA, Russia, China, Israel, Italy, Great Britain and Germany.
  • The risk of brain cancer is 20% higher in mobile phone users that have used it over 10 years and 200% higher when they holding the phone mainly from the same side of the head (Hardell et al. [2], [3])

"It's all a false alarm? No, the studies are competent, conclusive, powerful, scientific, factual and most certainly correct. The chicks are now dead as a dodo, the peaks in the EEG are obvious as are the dark spots in the brain, the leaks in the blood brain barrier, the breaks in the DNA, the irritation of the nerves. Red blood cells look like frog spawn, ears start to ring, the blood pressure goes up, and the level of concentration goes down These are the facts. The researchers who made those and many other findings are competent, they are well known and renowned the world over, coming from prestigious universities, institutes, laboratories, agencies, from the WHO, even from the mobile phone service providers themselves. False alarm? No way." Wolfgang Maes, German Institute for Building Biology [1]

“It took about 100 years for us to figure out that cigarette smoke was dangerous,” Carlo says. “It took about 80 years to figure out that asbestos was dangerous. [But] it took us five years to figure out that mobile phones are dangerous, once we started to look. What we’re talking about here is an effect that, at least in terms that are able to be recognized, greater than smoking and asbestos.” Dr. George Carlo, Founder Safe Wireless Initiative [4]

Why children and pregnant women should minimize the use of cell phones?

Due to their less developed immune system developing organisms are more vulnerable to the impacts of man-made radiation.

Many scientists now link the greater exposure of children and their parents to wireless radiation to the outbreak of childhood brain cancers and cognitive and behavioral problems.

Announcements for avoiding mobile phone use by children and pregnant women are among others published:

  • the International Commission for Electromagnetic Safety
  • the Russian Committee for the Protection on Non-Ionizing Radiation
  • the European Parliamentmobilephonekids
  • the Ministry of Education of Great Britain
  • the Cancer Institute of the University of Pittsburgh
  • The committee of the British Government Independent Expert Group on Mobile Phones (IEGMP) [5]
  • The Ministry of Health of Israel and France
  • The Finnish Committee for Protection from Radiation
  • the German Academy of Pediatrics [6] etc.

Read the announcement of the Russian Commission for Protection against Non-Ionizing Radiation [7] :

"For the first time in history, we face a situation when most children and teenagers in the world are continuously exposed to the potentially adverse influence of the electromagnetic fields (EMF) from mobile phones. Electromagnetic field is an important biotropic factor, affecting not just a human health in general, but also the processes of the higher nervous activity, including behavior and thinking. Radiation directly affects human brain when people use mobile phones.

Despite the recommendations, listed in the Sanitary Rules of the Ministry of Health, which insist that persons under 18 years should not use mobile phones (SanPiN 2.1.8/2.2.4.1190-03 point 6.9), children and teenagers became the target group for the marketing the mobile communications.

The current safety standards for exposure to microwaves from the mobile phones have been developed for the adults and don’t consider the characteristic features of the children’s organism. The WHO considers the protection of the children’s health from possible negative influence of the EMF of the mobile phones as a highest priority task. This problem has also been confirmed by the Scientific Committee of the European Commission, by national authorities of the European and Asian countries, by participants of the International scientific conferences on biological effects of the EMF.

Potential risk for the children’s health is very high:

  • the absorption of the electromagnetic energy in a child’s head is considerably higher than that in the head of an adult (children’s brain has higher conductivity, smaller size, thin skull bones, smaller distance from the antenna etc.);
  • children’s organism has more sensitivity to the EMF, than the adult’s;
  • children’s brain has higher sensitivity to the accumulation of the adverse effects under conditions of chronic exposure to the EMF
  • EMF affects the formation of the process of the higher nervous activity;
  • today’s children will spend essentially longer time using mobile phones, than today’s adults will.

According to the opinion of the Russian National Committee on Non-Ionizing Radiation Protection, the following health hazards are likely to be faced by the children mobile phone users in the nearest future:

  • disruption of memory, decline of attention, diminishing learning and cognitive abilities, increased irritability, sleep problems, increase in sensitivity to the stress, increased epileptic readiness.

Expected (possible) remote health risks:

  • brain tumors, tumors of acoustical and vestibular, nerves (in the age of 25-30 years), Alzheimer’s disease, “got dementia”, depressive syndrome, and the other types of degeneration of the nervous structures of the brain (in the age of 50 to 60).

The members of the Russian National Committee on Non-Ionizing Radiation Protection emphasize ultimate urgency to defend children’s health from the influence of the EMF of the mobile communication systems. We appeal to the government authorities, to the entire society to pay closest attention to this coming threat and to take adequate measures in order to prevent negative consequences to the future generation’s health. The children using mobile communication are not able to realize that they subject their brain to the EMF radiation and their health – to the risk. We believe that this risk is not much lower than the risk to the children’s health from tobacco or alcohol. It is our professional obligation not to let damage the children’s health by inactivity."

When are cell phones more likely to cause infertility?

Placing the mobile phone in the pocket of your trousers submits the sensitive genitals to an increased amount of radiation.

"In the past, we applied microwaves for birth control. Today we make phone calls with it. Go figure." Dr. Huai Chiang, advisor to the World Health Organization in radiation issues, Medical School of Zhejiang China [1]

EM Radiation Research Trust warns that carrying your mobile phone in your pocket can cause infertility.

The biggest problem is for those who use hands free and keep their cell phone in their pocket while they are talking to the phone.

What Apple writes in the safety instructions of iPhones

According to Apple, iPhone should used in a certain way so as not to exceed the safe levels of exposure to electromagnetic radiation!

Note that the permissible exposure limits to radiation from wireless devices are already hundreds of times higher than the limits proposed by various scientific bodies in recent years (see article on safe exposure limits here).

For the iPhone, Apple states the following (http://manuals.info.apple.com/en_US/iphone_4_important_product_information_guide.pdf):

"Exposure to Radio Frequency Energy iPhone transmits and receives radio frequency (RF) energy through its antennas.

The iPhone cellular antenna is located at the bottom edge of iPhone, to the left of the Home button. The Wi-Fi and Bluetooth® antenna is located at the top edge of iPhone, to the right of the headset jack. 

When carrying iPhone, keep it 1.5 cm (5/8 inch) or more away from your body to ensure exposure levels remain at or below the maximum levels.

Avoid cases with metal parts. 

Exposure to RF energy is related to time and distance. 

If you are concerned about RF exposure, decrease your total talk time on iPhone and increase your distance to iPhone by using one of the many hands-free options available, including the built-in speakerphone, the supplied headphones with built-in mic, or other third-party accessories."

Do not Hold Your iPhone Too Close to Your Head, Apple Says So

Should we take example from the insurance companies?

Insurance companies do not "close their eyes" to the issue of radiation as most people do. Already they take precautions, since potential claims for damage from artificial radiation can cost them dearly.

Especially on the effects of mobile phones, Guy Malyon, head broker insurance of Aon Global, notes that "The concern is that it could be the next big thing" while the insurance giant Lloyd's of London notes that "the number of reports on mobile telecommunications and its impact on health is immense, and the study findings are often conflicting" [8] .

Read the following interesting quote from the relevant article of the magazine "The Observer" [9] :

"Concern about the safety of mobile phones has prompted a leading Lloyd's underwriter to refuse to insure phone manufacturers against the risk of damage to users' health.

The move comes amid mounting concern about the industry's influence on research into the long-term effects of using a mobile.

The London market provides insurance for everything from aircraft to footballers' legs. But fears that mobile phones will be linked to illnesses such as cancer and Alzheimer's disease have prompted John Fenn, of underwriting group Stirling, to refuse to cover manufacturers against the risk of being sued if mobiles turn out to cause long-term damage.

Fenn said: 'There are people in the insurance market who close their eyes to the issue because they say there is no scientific proof of a problem. If you go back to asbestos, it "wasn't a problem" at one time either.' Asbestos claims helped bring the Lloyd's market to its knees in the early 1990s."

"The European Parliament is greatly concerned about the fact that insurance companies are tending to exclude coverage for the risks associated with EMFs from the scope of liability insurance policies, the implication clearly being that European insurers are already enforcing their version of the precautionary principle." European Parliament resolution 2008/2211 [10]

Do the products for mobile radiation protection work?

Products are supposed to "neutralize (?) electromagnetic radiation", "energy products that carry the appropriate information (?)" and several similar products that are placed on the mobile phones have flooded the market.

Most products do not achieve any measurable reduction of the mobile phone radiation.

Shielding cases for mobile phones theoretically limit the absorption of radiation from the side of the human body. However, there is some doubt about the real effectiveness because they hinder the reception signal of the cell phone, causing it to emit with more power.

Should i choose devices with low SAR;

SAR (Specific Absorbtion Rate) is the unit used to measure the amount of radiation absorbed by the human body when using a mobile phone.

For the SAR measurement, complex mathematical models are used, simulating the use of mobile in full force. But this does not take into account the effectiveness of each cell phone in real conditions of use.

In low signal conditions, a cell with a high theoretical SAR produces a lower SAR than another with lower theoretical SAR.

However, it is probably better to choose a phone with low SAR (<0,6) and avoid those with high SAR (> 1).

A list of SAR can be found on the websites:

http://sarvalues.com/the-complete-sar-list-for-all-phones-europe/ .

http://www.sardatabase.com .

Until we find a more reliable way of comparing the radiation of each model, we suggest you reduce your exposure to radiation of mobile by following the tips you will find below.

What is the difference of the 3G, 4G signals from the 2G;

Mobile phones to communicate with each other using existing mobile antennas networks.

The main difference between older and more widespread mobile networks 2G (GSM900MHz, GSM1800MHz) of the most modern networks 3G (UMTS 2100MHz) and 4G (1800MHz), is that the latter provide much higher data rates.

This means that when we signal 3G or 4G, you can surf the Internet, download videos etc with much higher speeds.

Does our mobile phone emit on average 28 times more radiation on 2G signal than when we have 3G signal?

Apparently, talking with 2G signal we receive far greater amount of radiation than when talk with 3G signal (on average 28 times more radiation according to research [11]!)

This is because the phones in 2G mode transmit at full power when trying to connect (maximum power 2W), ie at the start of a call and periodically to maintain contact with the nearest mobile antenna.

On the other hand when with 3G signal mobile phones emit the minimum radiation to maintain the connection (maximum power 125 - 250 mW).

So how come the 3G phones consume battery a lot faster?

When connected to 3G networks our cell phone consumes 40-50% more energy than when connected to 2G networks [12].

However, this is not related to the transmit power but to the more complex and energy intensive signal decoding which is necessary when talking with 3G signal.

Mobile phone safer use Tips

  • Keep you cell phone as far away from your head as possible during your calls
  • Better turn on speakers or use a hands-free cable.
  • Don't keep your phone in your pocket when you talk with hands free, as the genitals are particularly sensitive to wireless radiation.
  • Limit your talk time from a mobile phone using it when it is really necessary - better contact by SMS
  • Prefer fixed telephone lines, especially when you do long calls.
  • Prefer to make calls when you have 3G signal as the emitted radiation of the mobile is much less than when you talk with 2G signal.
  • Avoid using the phone in areas with bad signal where the phone transmitting at full power to connect (best signal is usually next to the windows).
  • Avoid using your mobile phone inside the car, in trains, boats, buses etc., because the radiation is beeing recycled internally reflected on metal surfaces, and as you move the mobile transmits at full power because it constantly tries to connect to the nearest antenna.
  • Using bluetooth headset is not recommended since it is a weak but continuous radiation source (exception: when you talk a lot on the mobile phone, especially in areas with poor signal, it is preferable to have the phone away and speak from bluetooth).
  • Divide your talktime holding the cell phone on both sides of the head.
  • If you use a smartphone, turn on the data or Wi-Fi antenna, only when you want to browse the Internet. Most applications, download data whenever you are these antennas on significantly increasing the radiation emitted by your cell phone.

Are mobile phones the biggest risk?

Mobile phones have been studied more than any wireless radiation sources because they are now used by billions of people and it is easier to carry out research on their biological effects. Also are the most recognizable radiation source.

However, their burden is usually transient and intermittent unlike dozens of other radiation sources emitting in 24 hours a day, in which we may be exposed for many hours, often without our knowledge.

Actual reduction of long-term electromagnetic daily burden can only be achieved if you avoid high levels of artificial radiation in all types of spaces such as a bedroom, office, living room, etc.

You can check your exposure to all kinds of electromagnetic fields with a radiation meter

What you don't know about the new "smart" power meters

Do you have "smart" meters installed your house? Are they safe? How much radiation do they emit? Do they health? Are they vulnerable to hackers attack? Are there alternatives? Are there ways to avoid them?

Smart grid - Smart Meters - Smart Devices - Smart home

New technology "smart" digital electricity meters will gradually replace existing analog type meters in all homes.

In many countries like the USA, Australia and others smart meters have already been installed in a big percentage of buildings.emfsafetynetwork   Copy According to a European Union directive each member country is obliged to install smart meters in 80% of the network connections until 2020.

Smart meters, are a main part of the smart grid (which includes smart devices), which provide consumers and electricity providers details of power consumption.

Smart meters, set cheaper cost of energy during hours with low energy consumption, which, at least in theory, is supposed to encourage consumers to use less electricity and shift use to off-peak hours. An important advantage of the smart grid is the fastest fault detection and recovery from blackout.

The big winners are the power companies, because the can lay off the extra staff previously needed to read the measurements from each buidlings analogue meters. Also they will be able to continuously adapt their pricing policies and immediately disconnect the power supply to consumers who have not paid.

On the other, the smart grid greatly increases the current levels of electromagnetic pollution, as smart meters and smart appliances already on the market, emit radiation either wirelessly or via the power cables to communicate with each other.

Moreover, as you will read below, many express concerns about the safety of the smart grid and the ability to be influenced by hackers, the increased bills for consumers, the violation of privacy, the many faults, increased installation costs, etc. 

 exipnospitiaktinovolia

Increased radiation emissions

For smart meters to communicate with the power companies various types of telecommunication technologies are used [4]:

  • RF carrier (Power Line Carrier - PLC and Distribution Line Carrier - DLC)
  • Internet Protocol (TCP / IP)
  • Wireless technology (GPRS / GSM)
  • Radio frequency (RF mesh)

If you have a smart meter installed in your home, ask the exact type, because each technology is different in terms of emitted radiation levels.

Smart meters which operate wirelessly have a transmitter, the radiation of which affects to some extent mainly nearby areas, depending on the strength and duration of emission. Their radiation is similar to the radiation of a wireless modem-router (wi-fi) or cordless phone, antennas that are widely used in indoors, usually broadcast 24 hours a day and in recent years have been linked to various health problems.

Smart meters which emit through the power cables, worsten the radiation emitted by the cables, by deforming the simple sine wave AC (phenomenon of "dirty power" or "dirty electricity"), which can be a problem for sensitive people, especially in homes with elevated electric fields from cables in walls.

"The adverse effects of electrosmog may take decades to be appreciated, although some, like carcinogenicity, are already starting to surface. This gigantic experiment on our children and grandchildren could result in massive damage to mind and body with the potential to produce a disaster of unprecedented proportions, unless proper precautions are immediately implemented." Paul Rosch, professor of medicine at New York Medical School [1]

Health Effects

Although radiation emissions vary significantly depending on the technology used, in many cases radation due to smart meters report far exceeds that of mobile phones, as shown by the report of the special nuclear policy lecturer at the University of California, Daniel Hirsch [5]. Since May 2011, the World Health Organization (WHO) has added radiation from mobile phones to the list of possible carcinogens.

Since the smart meters have been used only a few years and the types used vary from country to country it is still difficult to draw conclusions about the impact on human health. stopsmartmetersorg3   Copy However in recent years, research has linked the wireless radiation with insomnia, depression, brain cancer, testis, skin, salivary gland, male infertility, miscarriages pregnancy, leukemia, etc. 

The American Academy of Environmental Medicine, noting that many smart meters will broadcast 24 hours per day next to bedrooms, children's rooms and other sensitive areas, asks to reconsider the installation of smart meters until we explore the effects on human health [6].

According to surveys of EMF Safety Network in California [7] after installation of smart meters, the main health problems recorded were:

  • sleep problems (49% of respondents)
  • increased stress (43%)
  • headache (40%)
  • ringing in the ears (38%)
  • heart problems (26%)

Hacking risk

Although smart systems are encrypted, the encryption often fails.

Because of the many security problems, the former director of the CIA James Woolsey calls the smart grid "stupid" [8] because it is very vulnerable to hacker attacks with the aim of collecting personal information, changing billing, monitoring of tenants etc. Even simple jamming devices can sabotage the operation of smart meters.

According to the FBI, hackers attacks will likely cost energy providers $ 400 million a year [9]!

The network attacks are not imaginary scenario but a reality. The study conducted in 14 countries by the computer security company McAfee and the Center for Strategic and International Studies in Washington showed that things are getting worse [10]: "One of the more startling results of our research is the discovery of the constant probing and assault faced by these crucial utility networks. Some electric companies report thousands of probes every month. Our survey data lend support to anecdotal reporting that militaries in several countries have done reconnaissance and planning for cyberattacks on other nations’ power grids, mapping the underlying network infrastructure and locating vulnerabilities for future attack."

Experts from the University of Cambridge Computer Laboratory emphasize that hostile governments or terrorists might influence or even to interrupt the power supply to a smart grid [11].

Personal data breach

As observed by the European Commissioner for Data Protection (EDPS) smart meters will allow the mass collection of personal data and recording what household members in their private space are doing [12].

CIA Director David Petraeus admits that “Items of interest will be located, identified, monitored, and remotely controlled through technologies such as radio-frequency identification, sensor networks, tiny embedded servers, and energy harvesters — all connected to the next-generation internet using abundant, low-cost, and high-power computing”. With the rise of the “smart home,” you’d be sending tagged, geolocated data that a spy agency can intercept in real time when you use the lighting app on your phone to adjust your living room’s ambiance [13].

Faults - Fires

Experience in the use of intelligent systems in many countries shows that they are vulnerable to operating errors such as inadvertent activation of electrical appliances and a large number of fires has been associated with smart meters.

In case of failure and damage there is chance that smart meters-devices will not be not covered by the terms of your insurance contract [14].

Global reactions

The reactions to the installation of smart meters are worldwide with continuing resolutions, lawsuits etc.

Many cities seek the possibility of optional installation.

Testing programs, such as one in Australia, have failed, after the abandonment of the program than half users [16].

According to surveys of EMF Safety Network in California [17], 40% of people in homes which had a smart meters installed has complained to the power company and 94% would like to reinstall their old analog meters.

California also filed a class action by the consulting firm Wilner & Associates, against Pacific Gas & Electric (PG & E) on the legal basis of high radiation emissions, encroachment of property and health damage. The lawsuit asks for more than $ 2 million in penalties, $ 10,000 fine per customer and the obligation of PG & E to provide an analog meter at no cost to any customer who requests it.

Is there an alternative?

The most promising alternative is the use of optical fiber, providing high speed, data security and almost zero radiation.

However, this solution is not preferred since it has higher costs compared with wireless solutions.

How to limit the radiation from smart meters

If a smart meter is installed in your home we recommend that you measure the radiation with a high-frequency meter.

If you find that the radiation levels in your areas is high you can shield your walls, painting them with electromagnetic shielding paint that reflects wireless radiation to> 99% due to the special conductive composition.

If the smart meter does not emit wirelessly radiation but sends only through cable, then you can limit your exposure to electric fields from cables on walls, again by painting all the walls with electromagnetic shielding paint which is grounded to a wall electrical outlet. For buildings under construction there are other solutions (steel pipes etc.)

Which are the low frequency radiation sources that surround you?

Do you know what kind of radiation is emitted from power cables, building electrical installations, electrical appliances, electrical appliances, transformers and other sources that surround you? Are there any health risks?


lowfrequencysources

Where does low frequency radiation originate from

Electricity is transferred from power plants via high voltage lines (100-500kV) to substations. There the high voltage is reduced using transformers and electricity is transferred to medium voltage power lines (20-40kV). Again the medium voltage is reduced by transformers and electricity is transferred to low voltage power lines (110-480V) which finally bring electricity to our building electricity meter and from there to our individual electrical panel and the cables in walls, lights, wall outlets and electrical equipment.

All these conductive parts of the power network generate electrical alternative current (AC) fields due to electrical voltage. When electrical current flows through the conductors (when there is electricity consumption) AC magnetic fields are also produced.

The alternating current is called this way because the electrons in the live conductors switch movement direction 50-60 times per second (frequency 50Hz in Europe, 60Hz in the USA).

Are there any health effects?

According to the International Commission on Non-Ionizing Radiation, "The interaction of time-varying electric fields with the human body results in the flow of electric charges (electric current), the polarization of bound charge (formation of electric dipoles), and the reorientation of electric dipoles already present in tissue" and "The physical interaction of time-varying magnetic fields with the human body results in induced electric fields and circulating electric currents." [1]

Low frequency radiation has been linked to miscarriages during pregnancy, leukemia, breast cancer and skin, insomnia, thrombosis, damage to DNA, diabetes, multiple sclerosis, neurotic disorders, depression etc. Because of their link to childhood leukemia there have been classified as possible carcinogens in 1998 by the National Environmental Health Institute (NIEHS) [2] and in 2001 by the International Agency for Research on Cancer (IARC) of the World Health Organization [3].

“Very recently, new research is suggesting that nearly all the human plagues which emerged in the twentieth century, like common acute lymphoblastic leukemia in children, female breast cancer, malignant melanoma and asthma, can be tied to some facet of our use of electricity. There is an urgent need for governments and individuals to take steps to minimize community and personal EMF exposures.” Samuel Milham MD, MPH, Medical epidemiologist in occupational epidemiology. [4]

Low Frequency Radiation Sources 

Electrical devices

When we plug an electrical device to a power socket electric fields are produced due to voltage.

When we turn it on magnetic fields are also produced due to the flow of electricity.

Devices with bipolar plug which does not ground usually emit higher electric fields.

Higher magnetic fields are usually produced by devices:

  • with high consumption such as the kitchen, electric heaters, floor heating, boilers, etc.
  • which use low voltage so they contain a transformer such as: electric chargers, electric alarms, laptops, low voltage lights etc.
  • that contain electric motor as the refrigerator, blender, vacuum cleaner, fans, hair dryers etc.

Laptop radiation

Using laptop is an important source of exposure to artificial radiation for a large portion of the population.

Because of it's direct contact with our body electromagnetic fields emitted from the laptops expose us to radiation values that are frequently higher than the recommended safe exposure limits.

Types of radiation produced by laptops:

  • low frequency electric and magnetic fields due to the battery, the cables and the electric circuits
  • high frequency fields because of WLAN (wi-fi) antennas used to connect wirelessly to the internet.

There is research which links using laptops with DNA damage and degradation of the reproductive capacity.

See related article: EMF - an infertility cause you should be aware of

See more of information in our article about the effects of the wireless Internet.

Laptop radiation reduction tips:

  • unplug it from the outlet and use only with it's battery (static fields biologically less aggravating than alternating fields)
  • further the laptop away from your body by using an external keypad and placing it on a laptop stand, which also lifts the laptop screen to an ergonomically correct height and helps avoid future problems in the neck
  • turn off the wireless function of the laptop when your are not connected to the internet
  • replace the wireless connection with a wired internet connection by using a network cable to connect the laptop to the modem
  • alternatively use powerline adaptors (Broadband over power lines or power-line Internet). Put a Powerline adapter into an outlet and connect it to the router and install other Powerline adapters in sockets of remote rooms, where you want to have internet connection. This technology, however, is not the ideal substitute for wired ethenet networking because it transmits high frequency signals to the electric cables of the house (still in most cases better than wireless).

 Electronic devices

Many electronic devices deform the simple sinusoidal signal of 50-60Hz with harmonic of thousands Hz.

The phenomenon is called "dirty electricity" because it contributes to premature aging of electrical equipment. fluorescent light bulb

fluorescentDevices which 'contaminate' the mains are:

  • fluorescent and energy saving lamps
  • AC adapters
  • dimmer switches with electronic volume control
  • inverter air conditioners
  • inverters for photovoltaic systems
  • TVs, computers, microwave ovens etc.

The current widespread use of such devices alters the waveform of low frequency radiation, which means that the radiation we receive today from the cables of electricity, electrical installations and electrical appliances is more aggravating.

"Dirty electricity" has been associated with Attention Deficit Syndrome (ADD), multiple sclerosis and diabetes [5].

Cables of building electrical installations

The in wall electric cables produce electric fields towards lower voltage points (such as the human body) 24 hours a day and also produce magnetic fields when pwoer is consumed (when we turn on the lights, operate electrical appliances, etc.)

Deficient grounding or errors in the cable insulation often give unusually high measurements of electric fields.

High magnetic fields around the house often created due to incorrect wiring (such as neutral conductor connections from different circuits) which are a risk for fire or electric shock.

Electromechanical installations

High electric and / or magnetic fields may be emitted by:

  • electrical panels
  • transformers
  • lift mechanisms
  • generators (inverter) and chargers of photovoltaic system
  • boiler etc.

Building heating system

DSC05393

Houses using electric heating systems might have higher levels of magnetic radiation.

High electromagnetic fields are created by types of underfloor heating which do not use plastic water pipes but live conductors. The exception is underfloor heating with armpower transformerored power cables (which nullify electrical AC fields) and dual core (twin-core which reduces the magnetic AC fields).

Power lines and transformers: Health effects and safe distance

How much radiation do power lines, high voltage pylons and transformers emit? Which levels of electric and magnetic fields cause effects on human health and when are exceeded? Which source is the most common cause of elevated magnetic fields (not what you would imagine...)? What are the safe distances?


POWERLINERADIATION

How does the electricity grid work

Electricity is transferred from power plants via high voltage lines (100-500kV) to substations. There the high voltage is reduced using transformers and electricity is transferred to medium voltage power lines (20-40kV). Again the medium voltage is reduced by transformers and electricity is transferred to low voltage power lines (110-480V) which finally bring electricity to our building electricity meter and from there to our individual electrical panel and the cables in walls, lights, wall outlets and electrical equipment.

What kind of radiation do cables and transformers emit

All these conductive parts of the electrical network produce electric AC fields because they are under voltage and AC magnetic fields because current flows through produce. The alternating current (AC) is called that way because the electrons in the live conductors switch movement direction 50-60 times per second (frequency 50Hz in Europe, 60Hz in USA). 

Electric fields

high voltage

  • Electric fields are blocked by various grounded conductive objects such as trees, most building materials etc.
  • Elevated electric fields are usually recorded only outdoors near high or medium voltage lines.
  • Electric field sources are the cables of high voltage lines and not the pylons - pillars (radiation values are actually lower near the pillars, were the cables have the higher distance from the ground).
  • Most common source of electric fields in interior areas are the power cables located inside the walls and the electrical appliances and not the outside power lines. Faults in cable insulation or wrong connections (eg not grounding a circuit) may yield elevated prices. low voltage cables

power line 2Magnetic Fields

  • Magnetic fields penetrate most building materials unaffected.
  • Elevated magnetic fields are usually recorded near high and medium voltage power lines. Also near low voltage power cables, especially in densely populated areas (eg in 1st and 2nd floor apartments that are near overhead power lines o in underground or ground floor apartments when the power lines are underground).
  • According to statistics, the most common cause of high values of magnetic fields are low voltage power lines that bring electricity to every house. Only 23% of high values are due to high voltage lines.
  • This is because the magnetic fields depend on the amount of electricity that flows through the cables (ampere) and not on the voltage (Watt = Volt * Ampere). The low voltage cables can be overloaded particularly in densely populated areas. Moreover, the low voltage cables are usually found in smaller distances from residencies (high voltage cables usually have a minimum distance of 20 meters). power substation
  • DSC05393Transformers / substations create only locally elevated magnetic fields, which fall within a small distance (typically <5 m). However, the low or medium voltage cables starting from the transformers create typically elevated magnetic fields due to the large amount of current flowing. In houses away from the transformer the magnetic fields of low-voltage cables are lower, since most power has been distributed to the previous, closest to the transformer houses.
  • You can reduce your exposure to magnetic fields from cables and transformers by increasing your distance from them.
  • The magnetic shielding materials are metal alloys (not lead!) with very high magnetic permeability, but which have a very high cost (> 150 euros / m2) and other peculiarities. Their placement is certainly not recommended without prior measurement of magnetic fields.
  • Reduction of magnetic fields is possible, if the power lines are made underground or transferred to a more distant point (eg on the opposite side of the road). Although such solutions are not common you can contact your local power company and ask them if they can move the cables away.

Are underground power lines safer compared to overhead power lines?

In underground cables the electric fields are minimal because they are grounded and the magnetic fields decrease more rapidly because the cables have smaller distance between them.

However, because the underground lines are not obvious and are often in very short distances of high-use areas can cause high enough magnetic fields without the suspect on the ground floor or basement apartments or shops, in yards, gardens, pavements etc.

Why has our electromagnetic burden from the electricity network increased?

1. Because of the major expansion of the electricity network which has multiplied the report points to electromagnetic radiation.

2. Because of higher power consumption, which means that the existing power lines emit greater magnetic fields.

3. Because the radiation emitted by cables today has a more aggravating waveform. The extensive use of electronic non-linear load devices such as fluorescent lamps, AC adapters, dimmer electronic switches, inverter air conditioners, plasma TVs, photovoltaic systems etc. results in deformation of the plain sinusoidal signal of 50-60Hz mains with high frequency harmonics. This phenomenon is called "Dirty Electricity" because it causes overheating of the neutral conductor and premature aging of equipment. Some scientists believe that the new waveform of the power grid is particularly burdensome for humans [3] .

Does radiation from the power grid affect human health?

  • According to the guide of the International Commission on Non-Ionizing Radiation [4] , the interaction with the alternating electric field causes electric charges to flow in the human body and the reorientation of electric dipoles in the tissues, while magnetic fields cause electrical currents stimulating the nerve, muscle and sensory cells.
  • Previously there was the opinion that low frequency radiation at low intensities do not have enough energy (photons) and therefore our body could not distinguish them from the natural electromagnetic waves produced by the body (thermal noise).
  • But research since 1977 (Adey and Bawin) has shown that organisms can react to exogenous electromagnetic signals of very low intensity and experience an even greater reaction to them than from stronger signals.
  • The explanation of the phenomenon of cell amplification of an exogenous signal gave in 1994 at the Gilbert and Rodbell the Nobel Prize. The G proteins integrate multiple signals outside the cell and activate various cell amplification systems. Because of these, a single photon of electromagnetic energy is sufficient to start the massive calcium entry into the cells, activating several biological functions [5].

Recent research

Most studies that have taken place are addressing magnetic fields which are emitted from power lines, transformers and other sources.

Studies have linked the low-frequency radiation with miscarriages, leukemia, skin cancer, multiple sclerosis, etc.

Due to their connection with childhood leukemia, the magnetic fields are classified as "possible carcinogens" in 1998 by the National Environmental Health Institute, USA (NIEHS) [6] and in 2001 by the International Agency for Research on Cancer (IARC) of the World Health Organization [7].

“Very recently, new research is suggesting that nearly all the human plagues which emerged in the twentieth century, like common acute lymphoblastic leukemia in children, female breast cancer, malignant melanoma and asthma, can be tied to some facet of our use of electricity. There is an urgent need for governments and individuals to take steps to minimize community and personal EMF exposures.” Samuel Milham MD, MPH, Medical epidemiologist in occupational epidemiology. [8]

Childhood leukemia

  • A study by Ahlbom [10] recorded a statistical doubling of childhood leukemia in children exposed to daily average magnetic field values greater than 400nT.
  • Other research (Greenland [11] ) recorded a doubling of leukemia with even lower average exposure> 300nT (values> 300nT are not at all unusual in densely populated areas because of overloaded low voltage cables!)
  • Study of 2005 (Draper [12] ) recorded a 70% increase in childhood leukemia in distance <200 meters from high voltage cables and 23% increase in distance <600 meters.
  • Since magnetic fields at distances> 200m from high voltage cables are unlikely to be elevated (at least because of the high voltage cables), it is likely that the increased leukemia is due to other phenomena, such as ionization of the micro particles in the atmosphere. 
  • High electric fields around the high voltage lines, charge micro particles in the air (Corona Ions Effect) increasing the likelihood of adhesion to the skin and lungs [13] .The problem can be significant in areas with high atmospheric pollution (e.g. next to busy roads, in factories, were crops are sprayed). The charged particles can travel with the help of air up to 5 km away.
  • Research at the University of Bristol [14] showed that the presence of high levels of low-frequency electric fields, as near high voltage cables, increases up to 18 times the accumulation of radon particles. Elevated radon levels are associated with lung cancer (you can easily measure the radon levels in your area by buying a radon meter).

 highvoltageradonradiation

 Melanoma

  • Study of 2003 (Tynes [15] ) concluded that there is evidence to link exposure to magnetic fields with malignant melanoma.

Neurodegenerative diseases

  • After analysis of 2008 (Garcia [16] ) showed a significant increased risk of Altzheimer depending on exposure to electric and magnetic fields.
  • Other research ( Feychting [17] ) concluded that exposure to low frequency electromagnetic fields "increases the risk of early-onset Alzheimer's disease" and "may represent a late-acting influence in the disease process"
  • Increased risk of amyotrophic lateral sclerosis (ALS or disease of Lou Gehrig) has been shown in studies by Håkansson [18] and Ahlbom [19]. This disease is a progressive neurodegenerative disease that affects the nerve cells in the brain and spinal cord, causing muscular weakness, disability and eventually death.

Childhood obesity

  • Recent study [20] states that "Maternal exposure to high magnetic fields during pregnancy may be a new and previously unknown factor contributing to the world-wide epidemic of childhood obesity/overweight."

Childhood asthma

  • 15% increase in childhood asthma cases per 100nT increase in the exposure of the mother to magnetic fields was shown in a 2011 study [21].

Miscarriages

  • At least two studies have linked exposure of pregnant women to elevated magnetic fields with miscarriages during pregnancy [22] , [23].

What are the safe limits of exposure to low frequency magnetic fields?

In most countries the legislation issue safe limits based only on heating of tissues and many scientists consider this tactic outdated due to the recent surge of sources and new scientific data.

In recent years various scientific institutions have proposed new much lower exposure limits, which are based on non-thermal effects of radiation that appear to lead to health consequences. More about the safe levels of exposure to artificial radiation..

Most recommended exposure limits in recent years suggest that our daily average exposure should not exceed 10 Volt / m for electric fields and 200 nT for magnetic fields, values sadly not only exceeded near high voltage cables but often also near low voltage cables, transformers, electrical panels and various electrical appliances.

What is the safe distance from high voltage power lines?

In most countries the legislation permits safe minimum distance of residencies form high voltage lines around 200-25 meters.

However the proposed limits for exposure to electromagnetic radiation can be exceeded also in longer distances.

Elevated electric field values can be recorded at a distance> 200 meters. However because these fields are blocked by various grounded conductive objects such as trees, most building materials etc. so we can record low electric fields even in smaller distances.

The prices of the emitted magnetic fields dependent on electric loads of specific power lines, the spacing of the current carrying conductors etc. Just below and next to high-voltage lines is most likely that we will have magnetic field values many times higher from the recommended safe limits and the averages (70nT in Europe and 110 in the USA according to the World Health Organization). 200 meters are a good safe distance, which usually ensures values corresponding to the population average. Depending on the loads served by each line we can record normal levels even 50 meters or less from the cables.

How to measure the radiation from power lines and transformers?

High electric fields are emitted by high voltage lines but because they are grounded from most building materials (exception = wooden houses) they usually do not enter the interior of buildings and measuring them is more meaningful outdoors.

Magnetic fields on the other hand penetrate all areas since they are unaffected by most building materials.

You can measure low frequency electric and magnetic fields with a low frequency radiation meter.

Heating systems comparison (infrared, electric, gas, etc) - Safety, radiation, disadvantages

What you should know before choosing a heating system. What are the advantages and disadvantages of alternative forms of heating (infrared, electric, solar, geothermal, ions, etc.)? Which is more economical? What effect do they have on health, environment and economy? Which produce higher levels of electromagnetic radiation?


 tropoithermansis

All heating systems have advantages and disadvantages.

Although for many the main heating systems selection criteria is economic, in our article we will try include other parameters as well and also focus on which heating systems produce more radiation and have a potential impact on health (which may cost more in the long run). Generally:

  • Systems that heat using electricity, produce more artificial electromagnetic fields locally and through raising the magnetic fields that are emitted through the electrical grid (low, medium and high voltage transmission and distribution cables) but also pollute the environment since still in many countries electricity production is still based coal burning.
  • Systems operating with fossil or "renewable" fuels produce carbon dioxide, microparticles etc. polluting the atmosphere and the house interior (when there is no adequate ventilation).
  • Systems that produce hot air, heat the space unevenly, lift dust, need regular maintenance / cleaning of germs so they create problematic comfort conditions, particularly for people with allergies or respiratory problems.

However, if you choose based on the budget:

  • In addition to the original acquisition cost, consider the operating and maintenance costs.
  • Be cautions when reading various operating costs calculations, which do not take into account the significant differences in the efficiency of each equipment and the actual conditions of use.
  • Beware of the return of investment times that manufacturers of heating systems give! If you live in a small house and / or do not have great need for heating / cooling then the payback times and may be much greater than those advertised.
  • Some systems can be used for cooling, so will save money from purchasing a separate cooling equipment.
  • All heating technologies become more efficient and economic over time, while new heating technologies a continuously presented. If you are in no hurry to invest in a new system, waiting some time could mean improved technological solutions with better economic terms.
  • Keep in mind that the prices of the different fuels which basically determine the operating costs of each system are constantly changing depending on the existing conditions and availability. Consider the prospects of each type of fuel in our country long term (eg are gas supplies in your country enough to last 5 years or 50 years?).
  • The only solution to reduce heating costs, with zero particles, radiation emission and operating costs is the thermal insulation of your home!

Other things to consider:

  • How much useful space of your area is occupied by the machinery each type of heating
  • How easily available and is storable the fuel is
  • What are the maintenance and cleaning needs of each heating equipment

glass numbers 1Heating with electricity (electric)

Main types of electric heating are electric radiators, heaters, convectors, heating panels, electric boilers, fan heaters and air conditioners. The main advantages are:

  • There is no need to store fuel
  • The equipment normally occupies little usable space
  • Small equipment maintenance needs
  • Electricity is (almost always) immediately available

Electric heating and electromagnetic radiation

Switching to heating systems that use electricity has resulted in increased population exposure to low frequency electromagnetic fields.

Low frequency radiation has been linked to miscarriages, leukemia, breast cancer and skin, insomnia, thrombosis, damage to DNA, diabetes, multiple sclerosis, neurotic disorders, depression etc.

Local high emissions

Locally, near each electric heating equipment we frequently record elevated low frequency electric and magnetic fields.

Magnetic fields are typically higher in equipment with high wattage, especially in systems using motors (eg. fans) or transformers.

Electric fields are higher when not the heating device is not grounded (has a bipolar plug) or the building has no functional grounding.

Typically the radiation values are reduced to normal levels at distances> 1 m, so we recommend that you avoid spending too much time in the immediate vicinity of any heat generating device that operates with electricity (some sources may anyway cause burns within walking distance).

Higher magnetic fields everywhere

power line 2The use of electric heating significantly increases the consumption of electricity, which means that all power cables of the electric grid (low,medium and high voltage lines) will emit much higher magnetic fields especially when there are extreme low or high temperatures.

Dirty electricity

Please note that the electromagnetic fields generated by the power cables today are different from those in the past, not only in quantity but also in quality.

The previously simple sinusoidal signal of the electric network (50-60Hz) is now distorted by higher harmonic frequencies (thousands Hz) due to the extensive use of electronic non-linear load devices such as fluorescent lamps, AC adapters, dimmer electronic switches, inverter air conditioners, plasma TVs, photovoltaic systems etc.

This phenomenon is called "Dirty Electricity" because it causes overheating of neutral conductor and premature aging of equipment. Scientists believe that the new wave of power grid is particularly burdensome for humans [1] .

“Very recently, new research is suggesting that nearly all the human plagues which emerged in the twentieth century, like common acute lymphoblastic leukemia in children, female breast cancer, malignant melanoma and asthma, can be tied to some facet of our use of electricity. There is an urgent need for governments and individuals to take steps to minimize community and personal EMF exposures.” Samuel Milham MD, MPH, Medical epidemiologist in occupational epidemiology. [2]

To determine if the areas where you spend most of your time, there are high prices due to radiation from your heating system or your neighborhoods power cables you can buy a simple to use low frequency radiation meter.

Is electric heating "greener"?

Copy of nuclear2Many have the impression that electric heating is ecological because the electrical heaters do not operate by burning fuel and produce no local carbon dioxide or other dangerous pollutants inside the houses.

However, power plants (which make powering the electric heaters possible) mainly use fossil fuels (lignite) and are responsible for a big percentage of greenhouse gases production in many countries.

For example burning coal to produce electricity produces carbon dioxide, microparticles, steam emitted from the cooling towers of the production units and other pollutants.

Some comparative Greenpeace tables [3] show that the production of carbon dioxide due to air conditioners heating (electric) is greater than that produced by oil heating.

It is no coincidence that the Nordic european countries have limited the use of electricity as a heating source and have turned to other systems [4].

Shouldn't we turn to electric heating anyway since fossil fuels will soon will be exhausted?

According to estimates, world oil reserves, natural gas and coal are sufficient to cover our need for 40 years, 70 years and 200 years respectively [5] .

Also, the burning of fossil fuels produces numerous harmful pollutants and the fact that most countries import oil and gas from foreign countries means that their prices are volatile and are influenced by many unpredictable political and economic factors.

The future of energy production for many is the generation of electricity from renewable sources (photovoltaic, wind, geothermal, hydro) and the European Union has set a target to cover 20% of energy consumption by renewable sources by 2020.

However, electricity production from renewable sources, means greater electromagnetic fields emission from the power grid with an even more aggravating waveform (with high frequency harmonics) than in the past.

Using renewable sources in a very local level, would limit considerably the transmission losses and the need for expansion of the electricity network.

Other solutions

Given the large financial requirements for infrastructure of renewable energy sources and the present economic crisis, some countries should at least temporarily consider other solutions.

Fossil fuels are still significant advantages in relation to renewable energy sources, like the fact that they can easily be stored and meet the fluctuations in energy demand.

Some great advantages offers the heating solution that utilizes the generated heat from existing thermal power plants (which would otherwise be wasted) to carry hot water through insulated pipes to the radiators of an entire city. In this case with only one burner and one boiler in power plants an entire city can be heated which means much less production of pollutants and zero production of artificial electromagnetic fields. Consumer will also save money from buying a burner, a boiler and other equipment (excluding radiators) and save on maintenance costs. This system is implemented in many countries.

Electric radiators, convectors, heating panels

  • Contain resistors which are heated
  • It is cheap but has high operating costs
  • They are quite and produce heat immediately
  • Better for more localized heating rather than for heating the whole house

Halogen, quartz infrared heaters etc.

  • imagesIn addition to high operating costs they also require special attention to avoid burns and fire
  • Also the light produced is annoying to humans

Air fan heaters, air conditioners, fancoils

  • The main problem is that they produce hot and dry air that lifts the dust from the floor, creating problematic comfort conditions, particularly for people with allergies or respiratory problems
  • They are also noisy, they heat the spaces heat unevenly (cold floor - warm roof) and the space quickly cools after shutdown (unlike conventional radiators)
  • The inverter technology in air conditioners has reduced power consumption and noise levels compared to conventional older type ac units
  • Fancoils in combination with a heat pump offer reduced energy consumption
  • Air conditioners need regular maintenance of filters

Electric boilers

  • Electric boilers contain electrical resistors that heat the water they contain and get transferred to the radiators
  • They are quiet, have little maintenance and do not occupy much space, but have high operating costs

Electric ion boilers

  • They have reduced consumption compared to conventional ones because they ionize water which makes it heat rapidly
  • There are several technical difficulties in their implementation (pipe and radiators corrosion etc.) so it is recommended to use specialized company for the installation

Underfloor heating with electric resistances

  • Underfloor heating systems using electric heating elements instead of water pipes, usually create high electromagnetic fields with which we come into direct contact
  • The exception is underfloor heating with armored power cables (zero electrical AC fields) and dual core cables (twin-core cables reduces the magnetic AC fields)

Electric storage heaters 

  • storageHowThey contain heat resistors are powered during the night (with usually reduced electricity prices) and heating the high thermal mass materials they also contain (bricks)
  • The firebricks transfer the heat to the space in the form of infrared radiation which is considered the healthiest form of heat (similar to the heat of the sun)
  • Despite its use during reduced tariffs hours they still consume a lot of energy
  • Also many storage heaters do not heat the area quickly (the area might be warm after some hours)
  • The heaters emit electromagnetic radiation fields at night when they are charging so you should avoid placing them at a distance of <1 meter from beds

Infrared heating panels 

  • Electric resistors produce long wave infrared radiation which is considered the healthiest form of heat
  • The panels surfaces are coated with special materials (ceramics, carbon polyamide, graphite, quartz crystals, etc.) that absorb the generated heat and radiate it in space
  • Infrared radiation directly heats your body and objects without warming the air. Especially objects with high thermal mass (eg bricks, ceramic tiles) store heat and gradually attach to space
  • Because it does not heat the air but the building materials, it is important to have good wall thermal insulation or else as much of the heat stored in the walls and ceiling will be quickly lost to the environment
  • Because they do not heat the air, the feeling you get when you operate them in a cold house is like when you're out on a cold winter day and the sun warms your skin and your clothes but not the air.
  • Also there must be visual contact with the panel to warm your body. For this reason, many prefer to use infrared panels for spot heating, not for heating the entire house
  • Compared to oil or gas heating, infrared panels have lower purchase costs and do not occupy much usable space
  • They have a reduced consumption with respect to the most electrical heaters
  • They help to reduce the humidity in the walls
  • They are simple to install and require no maintenance

Are infrared panels safe? Dont they emit dangerous ionizing radiation?

Infrared radiation is equivalent to the heat from the sun, the fire and the heat produced by the human body.

It is close to the spectrum of ionizing radiation, with a bit lower frequency than UV radiation and natural sunlight.

However, even the ionizing radiation (which exists in the environment since there is a man) in a specific amount has a beneficial effect on the human body (e.g., UV radiation helps to produce vitamin D hormones, radioactive baths around the world are used for therapeutic purposes). Read more in our article on ionizing radiation..

Infrared radiation is believed to help improve blood circulation, also in arthritic and muscle problems, detoxification etc. and is used in incubators premature babies.

In our opinion the modern man who spends small amount of time in nature and the sun may have greater need of the beneficial action of infrared radiation.

An important advantage of infrared panels is that they do not create unhealthy air currents carrying dust and microorganisms in space (as air conditioners do) and help to reduce moisture and mold growth.

There is research [7] claiming that acute and chronic exposure to ultraviolet radiation could cause eye damage. For this we suggest that you avoid long exposure with direct visual contact with the panel (better to see the panel from the side or rear), especially in the case of cheap infrared halogen heaters that produce light which is also annoying for the eyes.

High temperature panels (~ 300 °C) must be placed high in order to avoid burns or other accidents.

Infrared panels also emit low frequency electromagnetic fields that are not considered biologically friendly to humans. Our measurements with infrared panels showed elevated magnetic fields at a distance of <1 meter from the panels.

Alternative infrared heating systems which produce wholesome natural infrared radiation without artificial radiation is the heat from storage heaters (charged and then unplugged) and from high thermal mass fireplaces. chimney smoking

glass numbers 2chimneyHeating with combustion

Burning oil, gas, wood, pellets, etc. for thermal energy produces carbon dioxide capture, micro particles and other pollutants that contribute significantly to air pollution and global warming.

The effects of induced air pollution are individually larger when combustion takes place indoors with poor ventilation.

Oil burners - boilers

Oil is burned in the burner and the boiler heats water which through pipes reaches the radiators.

Benefits

  • oil is in most countries availiable
  • no radiation emissions

Disadvantages

  • High purchase costs (burner, boiler, piping, radiators etc.)
  • Occupies much usable space
  • High operating costs
  • High and constantly changing fuel costs
  • Needs maintenance
  • Oil is not a renewable energy source
  • Needs supply through tankers

How to reduce your operating costs

  • Regular boiler burner maintenance (at least annual)
  • Repair defective piping insulation
  • Replacing old boilers which have very low efficiency (30-40%) with new, more energy-efficient systems that operate with an efficiency of> 80% (eg condensing boilers or high efficiency boilers that recover the lost thermal energy from the combustion of fuel)

Gas burners -boilers

Benefits

Natural gas compared with oil:

  • is usually cheaper
  • is availiable continuously available and does not need to be prestored
  • typically uses younger generation boilers with better performance
  • it has faster response to temperature setting

Disadvantages

  • need a developed distribution network that brings gas to your neighborhood
  • Monthly fee for gas supply
  • High purchase costs (burner, boiler, piping, radiators)
  • High operating costs
  • Constantly changing fuel costs
  • Needs maintenance
  • Natural gas is not a renewable energy source

Biomass burners boilers (wood, pellets, etc.)

Biomass are materials of organic origin like wood, pellets (compressed pieces of various plant products, sawdust, etc.), bioethanol (alcohol produced from plants such as sugar beet and corn) etc.

Benefits

  • Biomass is considered a renewable energy source because whatever is cut can be replanted
  • There is possibility of domestic production
  • Lower cost consumption of oil and natural gas (depending on the efficiency of the boiler and fuel)
  • Relatively small operating costs

Disadvantages

  • Takes up large useable space (burner-boiler + storage)
  • High maintenance when used low quality wood or pellets
  • Continuous feedback need (depending on the type of biomass and the burner)
  • Regular cleaning

Is biomass really ecological energy source?

Biomass is considered not to contribute to increased carbon dioxide in the atmosphere (CO2 neutral) because the carbon dioxide produced had already been removed from the atmosphere during growth of the tree or plant from which it originated or because a new tree or plant will be planted in place of the cut.

But is this really what happens? Alex Scrivener policy officer at the World Development Movement, claims that [6] :

“Substituting biomass for fossil fuels sounds like the easy solution to climate change. But in reality, it leads to land grabs, the destruction of rainforests, and severe food shortages where land is used to grow fuel instead of food. And the idea that biofuels are ‘carbon neutral’ is a myth."

In reality, biomass is mainly imported from third world countries (imported CO2 without local replenishment) were large areas often never replanted.

Even if replanted, the new trees take year to replenish the lost oxygen.

Also the use of biomass as fuel leads to the rise of illegal logging and monoculture for biofuels (which may have an impact on local biodiversity and soil).

However our opinion is that biomass can be a good alternative to fossil fuels, provided the production is controlled and permitted only when the necessary conditions are met.

Fireplaces and stoves, biomass (wood, pellets, vioaiathanolis) 

franco belge monaco stove bBenefits

  • Biomass is considered a renewable energy source if replanted after cut.
  • There is possibility of domestic production
  • Lower cost that oil and natural gas
  • Aesthetically beautiful

Disadvantages

  • It is necessary to have ventilation and also supply fresh air
  • The existence of a burner inside the house is dangerous
  • Temperature control weakness
  • Regular and difficult maintenance
  • Continuous feed need
  • Various weather conditions (high outside temperature, windy, etc.) can make the evacuation of the combustion gases difficult (chimney smoking)
  • Storage need

Oil stoves, kerosene, gas, wood, pellets etc.

  • Used mainly for spot heating
  • They are usually a cheap option but their quality varies considerably from model to model
  • Exhaust ventilation necessary
  • Beware of leakage in gas stoves

Regular fireplaces

They are open and not at all recommended because:

  • They have very poor yield 10-30% and consume much fuel
  • They produce many pollutants
  • They consume much oxygen so you must have an open window
  • They need constant supervision

Energy efficient - thermodynamic fireplaces / stoves

  • Such fireplaces close with some fireproof glass. Thus, the wood burns with less air and the degree of efficiency reaches 70-75%
  • They need les fuel and reduce the pollutants and air loss from the house
  • They do not need constant supervision
  • In thermodynamic or ecological fireplaces an additional mechanism that reburns the exhaust gases further increases the efficiency of the fireplace and minimizes pollutants
  • May have vents at the bottom, were cold air enters and then is heated (through airways - not in contact with the exhaust gases of the outbreak) and comes from the top vent hot
  • By using fans and air ducts you can also warm other rooms.This duct system inside the houses is not recommended because it produces hot and dry air that lifts the dust, creating problematic comfort conditions, particularly for people with allergies or respiratory problems.Also it is difficult to purify the airways from dust and germs
  • However, if you choose to have hot air from the fireplace, choose a fireplace in which the air is drawn from outside (fresh air) and not from inside the house
  • A better solution is to connect the fireplace to radiators through water pipes

Bioethanol fireplaces

  • The fireplaces that burn bioethanol (fluid) do not make smoke and only emmit small amounts of carbon dioxide so it is usually open-ended and does not work with chimney
  • Low selling price compared to other fireplaces and is aesthetically very beautiful

High thermal mass fireplaces

  • MASONRYHigh thermal mass fireplaces (masonry heaters) are built with ceramic materials, bricks, marble and other high heat capacity materials
  • The combustion takes place with closed hearth, with a small amount of fuel and minimal exhaust gases are produced from the chimney
  • The hot air which is generated heats the bricks which store the heat and emit it in the form of healthy infrared heat for several hours after the fire goes out
  • Usually the large thermal mass fireplaces occupy a large area and are placed in the center of the room
  • Their problem is that after you start the fire it takes a while for the room to get warm
  • Also, after you turn the fire off it takes a while for the room to get to normal-low temperature
  • It is in our opinion one of the most hygienic ways of heating that exists from antiquity (Roman hypocaust) and is very popular in the Nordic countries

glass numbers 3Heating with heat pumps

Heating with heat pumps are maybe the heating system with the lower operating costs since they produce heat which they derive from the environment with a relatively small use of electrical power (depending on conditions).

They save space (no boiler and fuel storage), do not generate combustion pollutants in housing and can also be used for cooling.

What determines how economical their function is, is their coefficient of performance (C.O.P.), which is usually high (3-6). For example C.O.P. 5 means practically that for every kilowatt of electricity consumed, they produce five times the thermal energy.

The smaller the temperature difference between the heat pump source (air, water, earth) and the heat medium of the terminal units (for example, water in radiators) the less the electricity needs to be consumed.

Therefore, heat pumps are ideal when there are low temperature systems (eg radiators with large panel-type surface or floor heating or fan coils). Low temperature systems (30-40 degrees) require less energy to heat the room in relation to traditional radiators panels (70-80 degrees).

Air Pumps

  • cbglex0dThe most common heat pumps are the pumps that use outside air. They are an economical type of pump, however their performance degree drops significantly increasing power consumption, when there is a large temperature difference with the outside air
  • That is, the air heat pumps are spending much power with very low outside temperatures, or when you adjust the thermostat at very high temperatures inside
  • Also the outdoor units of air pumps occupy space outside, aesthetically damage and are vulnerable to theft
  • The air-to-air pumps produce hot air via fancoils or airways. Air-to-air pumps are air conditioners. The inverter type have more economical operation
  • Like all corresponding systems that heat the air, they are not considered healthy because they produce hot and dry air that lifts the dust from the floor, creating problematic comfort conditions, particularly for people with allergies or respiratory problems
  • They are also noisy, heat the space unevenly and require regular maintenance of the filter
  • We recommend to look for systems that also offer moisture regulation as well as entrance of fresh air in the room
  • The air-water pumps heat water. If you have traditional radiator panels you will need a high-temperature heat pump. If you have large radiator panels or floor heating you will need a low-temperature heat pump (most economical operating costs)

Geothermal pumps

  • res geo earth cut awayThe pumps with the highest degree of performance and the lesser operating cost is geothermal, which harnesses the heat in the ground several meters below the surface of the earth or the heat of groundwater (underground temperature shows small variations in contrast with the outside air)
  • The disadvantages of geothermal pumps is the high cost of installation and the need for space 40-100 sq.m. for drilling

Our suggestion!

The ideal choice in our opinion for new homes is the combination of geothermal heat pump with underfloor heating and undefloor or underceiling cooling. If additionaly there is a combination with a photovoltaic system you can annihilate operating costs for heating. A system of water pipes in the floor:

  • creates optimal conditions of thermal comfort in relation to all systems and evenly distributes the heat to the space
  • does not occupy useful space inside the house and gives you freedom in the layout of the house
  • has silent operation
  • works even more economically when the floor has large thermal capacity ceramic tiles (as opposed to the wooden floor)
  • does not lose heat quickly after you turn it off
  • takes long to heat the room after it becomes operational (unsuitable for vacation homes)
  • if there is damage the is repair difficult (although installation companies give many years guarantee and damages are rare)
  • It is the ideal system for cooling a space

glass numbers 4Heat from the sun

  • KSW 5Kollektoren R1Solar heating systems are functioning similarly to the water heaters,however, require much larger collector area
  • the water is heated by solar panels used on radiators
  • they have high installation cost
  • they have economic operation mainly where there is good thermal insulation and low temperature radiators (large-area radiator type panels or underfloor heating)
  • the system is problematic on days where there is not enough sunshine so it is anyway necessary to have an auxiliary boiler

glass numbers 5Insulation: The best solution to reduce heating costs

The inner or outer insulation of a building is the most reliable and ecological solution to reduce heating costs.

It restricts the entry of cold in the house and also reduces the heat losses to the environment.

In building with no thermal regulation you can achieve up to 50% reduction in heating and cooling costs.

Basic insulation solutions are:

  • Thermal insulation of external walls and roof : This is done internally or externally with materials such as glass wool, cork, rockwool, polyurethane, perlite etc.
  • Double glazing or thermally insulated windows : In this case do not forget to ventilate your room regularly during the day.
  • Thermal insulation of pipes and radiators : The insulation of pipelines going through outdoors or spaces not required for heating is necessary. Also use reflectros (eg aluminum) for radiators in contact with the outer wall.

Alternative proposals for reducing heating costs

  • Dress warmer
  • It is not necessary to dress with t-shirts at home even during the coldest winter days! Try to dress warmer before turning on any heat source.
  • Use a thermostat
  • Use thermostats (where feasible) to avoid unnecessary operation of heat sources. Set the thermostat at normal temperatures (20 to 22 day and 16 to 18 hours). Don't ask for 25 degrees when outside the temperature is 5 degrees!
  • Take advantage of the sun's heat
  • If your house has an opening to the south (for the northern hemisphere - the opposite for the southern hemisphere), leave it open during the day so that abundant infrared heat enters from the sun. Especially if you have floors with high heat capacity (eg ceramic tiles) this heat will be stored and transmitted after dark.
  • Other passive solar systems are more easily incorporated into new homes are solar patios (indoor spas with windows in the roof) and solar walls (glazed outside the walls which function as greenhouses accumulating heat from the sun and transferring it inside the building). In such cases it is advisable to have the possibility of selective shading so that there is no unwanted increase in temperature during the summer months.

What you don't know about the effects of radioactivity

What radioactive sources surround you what are their effect on your health? What does the Radiation Hormesis theory claim; Which kind of ionizing radiation is a proven carcinogen? Are there risks from the nuclear accident in Japan? How to protect yourself? How to measure the radioactivity levels in your area?


 radienergeiaepiptoseis

Radioactivity = Ionizing radiation

Everything in nature consist of atoms. Radioactive atoms are unstable because their nuclei have a lot of energy.

During attenuation to more stable forms they emit radiation (alpha particles, beta and gamma rays) which is called ionizing because it ejects the electrons from other atoms forming ions.

Ionization activates the production of free radicals in the human body cells and may cause changes in the structure of the chromosomes of the cell membrane (mechanisms associated with cancer development).

Elevated levels of radiation can cause nausea, vomiting, burns, hair loss, infertility, impairment of the immune system and an increased incidence of certain types of cancer death.

Especially for radioactive radon gas, which is the main source of population exposure to radiation, the World Health Organization [1] states that it is, after smoking, the second most important cause of lung cancer (the most common cause of cancer death [2]).

Where do we receive radioactivity from?

  • 55% from the radioactive radon gas that gushes from the earth
  • 15% from medical applications (X-rays, scans, tumor irradiation etc.)
  • 11% from radioactive isotopes that are naturally present in our body itself or spending through food
  • 8% from radioactive materials in the earth's crust
  • 8% from cosmic radiation (from the sun and space)
  • 3% from consumer goods (fire detectors, building materials such as granite, smoking, cooking gas, etc.)
  • <1% from nuclear plants, nuclear tests, transport of radioactive materials etc. [3]

Recent statistics from Germany show that due to the frequent mammograms, CT scans and similar medical procedures, the total amount of radiation we receive from artificial sources is now equivalent to that from natural sources [4].

Where do we often record elevated radioactivity levels?

  • Near building materials with high radioactive ingredients (eg various ceramic tiles, granite counters, bricks, cement, pumice stones of volcanic ash, phosphogypsum, etc.)
  • In food with radioactive residues (eg vegetables, milk, meat and fish from the affected areas of radioactivity in Japan and neighboring regions - anything produced after March 12, 2011). In watches that glow, pottery, ionization fire detectors etc.
  • In kitchens that run on natural gas
  • In water from wells
  • Near nuclear power plants and reactors, especially after a nuclear accident (for which the public may be informed too late, as was the case in the 1986 accident of Chernobyl).
  • In waste of industries, hospitals (nuclear medicine applications), etc.
  • In areas with very high altitude (higher levels of cosmic radiation)
  • In areas with higher levels of radon, thorium, uranium, etc. in the underground
  • In caves, hot springs and mines
  • In radiodiagnostic laboratories
  • In plants for cements, aluminum and phosphate fertilizers, oil drilling, power plants burning lignite, etc.
  • In airplanes during flight

How real is the risk of a nuclear accident today?

Copy of nuclear2Nuclear accidents are not uncommon.

So far they have been recorded more than 152 radioactive leakage incidents in nuclear plants, industrial plants, nuclear tests, etc. [5]

In many cases of nuclear leaks and accidents, such as Chernobyl, the public is informed too late, resulting in not enough time to take precautions.

With a radioactivity meter can you see first every increase of radiation levels in your area!

Today there are more than 438 nuclear power plants worldwide with many others under construction. You can check the nuclear facilities of each country here.

All countries using nuclear power argue that there is no risk but as Japanese specialist in nuclears Hiroshe Takashi says, if the reactors were so secure, they would not be built in remote areas, but in urban centers to avoid energy losses from transmission cables [6].

What factors are related to the effects of ionizing radiation?

Type of ionizing radiation

Alpha particles: particularly dangerous when ingested through eating or inhalation through the air (radon). They can easily be shielded even with a piece of paper.

Beta particles (or electron radiation): dangerous especially when ingested through eating or inhalation through the air. They can be shielded with a metal foil (e.g. aluminum).

Gamma rays: electromagnetic radiation emitted during radioactive decay (along with alpha and beta radiation) - they have high penetration and can travel several meters in the air. They can be shielded with thick cement, lead, steel etc. They are a big part of terrestrial radiation and, along with radon gas concentrations, they are the most important for building biology assessments.

X rays: very high frequency electromagnetic radiation generated when a strong electron beam bombards a metal inside a glass tube, which is generated mainly by artificial sources in medical diagnostics etc - they have high penetration and can travel several meters in the air. They can be shielded with thick cement, lead, steel etc.

Neutron radiation: high energy unstable elementary particles with no charge - they can be obtained only from sources that produce them freshly in the atmosphere, thunderstorms, ocean etc

Cosmic radiation: Mainly gamma rays but also neutrons, can be found especially several hundred meters above sea level.

Indoor VS Outdoor exposure

Scientists often do not distinguish between the external dose of radiation than we receive internally when we inhale or consume a radioactive material.

This is misleading since, as mentioned by the former secretary of the European Commission on Risk from Radiation is like comparing beeing warm next to the fire with swallowing hot coals! [7].

According to scientific theory, long-term exposure to very low levels of radioactivity (as a result of consumption of some radioactive elements) is a million times more harmful than the short-term outdoor exposure to high levels of radioactivity (Petkaou Effect) and is likely to be associated with the development cancer and other diseases. [8]

Attenuation time

A characteristic of many radioactive materials is the long half-life ie the time required for a radioactive element to lose 50% of its energy. These materials remain radioactive million years.

However, radioactive elements with long half-life (eg 700 million years uranium-235) have very slow decay rate subjecting us to negligible radioactivity compared to that obtained from nature or our own body (eg . Our potassium-40 in the body has a half life of 1.4 billion years).

Unlike radioactive elements with much shorter half-lives (usually released into the atmosphere from nuclear accidents), emit more radiation in a shorter period and affect more the cells of specific organs.

For example, radioactive iodine-131 (8 days half-life) is accumulated mainly in the thyroid and prolonged consumption can cause thyroid malfunction and / or cancer.

Respectively, cesium-137 radioactive element (which accumulates in muscles and fat) and strontium-90 (which accumulates in bones) have about 30 years half-life and when consumed they significantly affect our cells for decades (strontium -97 is associated with leukemia).

Radiation dose

The most common unit of measurement of radioactivity is the effective dose Sievert (Sv-Sivert) depending on the type of radiation (a, b, c, X, etc.) and the amount of radation absorbed ny the human body. Other radiation dose unit used is the rem (PEM) where 1 rem = 0,01 Sv.

In many, more reliable size of the effective dose for health effects prediction is the rate of effective dose usually measured in measured in mSv / h (micro sivert per hour).

High radiation dose values retained for longer are obviously more dangerous for humans.

Typical examples are the high levels of radiation following a nuclear accident which can be retained in an area for years.

What are the health effects of radiation exposure?

The Scientific Committee of the United Nations on the Effects of Atomic Radiation (UNSCEAR) [9] explains in detail the mechanism of action of ionizing radiation:

"When radiation passes through material, it causes ionization which can damage chemical structures. If the material in question is biological material (such as the cells that make up human organs and tissues) and if the damage occurs to critical chemicals within the cells (such as the DNA molecules making up the chromosomes within the cell nucleus), the cell itself can be damaged.

It should be noted that the cell and the DNA are undergoing physical and chemical damage all the time (e.g. from temperature fluctuations and oxidation processes). However the cell and DNA have mechanisms to repair damage. The radiation damage will usually be repaired by these normal cell repair processes; or the cell may be sacrificed. This is of not significance if the repair is successful or if the number of cells killed is not large.

However it is possible also that the DNA may be misrepaired; in the majority of cases, such mutated cells will also die. However there is a small possibility that the cell survives and the mutation in the DNA is replicated as the cell divides. This can be the start of a multi-step process that could eventually lead to formation of a cancer.

These various possible effects at the molecular, cellular and tissue level influence the overall outcome of a person exposed to radiation. The severity of any immediate effect will depend on the total amount of exposure to radiation within a given period of time-termed the radiation dose.

If a person is exposed to very high levels of radiation for a significant period of time and the accumulated dose is high, a large number of cells can be killed. This represents serious injury to the exposed person (e.g. skin burns, hair loss, sterility, damage to the blood-producing systems and the immune system). Depending on the dose, the exposed person can recover from the injuries, particularly if good medical treatment is made available quickly. But at very high doses, recovery is not possible, leading to death over days or weeks.

At lower doses of radiation, below the levels associated with early onset of injury and death due to cell-killing, an exposed population may show an increased incidence of certain types of cancer, years to decades later, compared with populations that were not exposed. In this respect ionizing radiation is a carcinogen similar to cigarette smoke and the incidence of cancer in a population increases with the radiation dose received. In scientific studies on animals, hereditary effects have been observed, but this has never been observed in human populations, though we can assume that it probably does occur in humans to a small degree."

How we measure radioactivity and what are the safe levels of exposure? What happens during pregnancy?

Most radioactivity meters record the rate effective dose of radioactivity, usually measured in measured in mSv / h (micro sivert per hour).

Normal radioactivity values in the environment are generally <0.3 mSv / h (eg 0.13 mSv / h is world average exposure to natural sources of radiation - except radon [10] and values greater than 0.4 mSv / h trigger radiation alarm in Finland).

The exposure limits set by the legislation are:

  • European level occupationally exposed 10 mSv / h (20 mSv / year - 2000 working hours per year) [11]

Potential health effects depending on the radiation dose rates [12]

  • 100 mSv / h: increased chance of illness
  • 100 000 mSv / h: nausea, vomiting (radiation sickness)
  • 1,000,000 mSv / h: increased chance of cancer
  • 10,000,000 mSv / h: organ damage and death within hours

The US Nuclear Regulatory Commission (NRC) identifies as high activity areas in nuclear power station or after a nuclear accident when exceeded 1,000 mSv / h [13].

Multiplying the dose rate with the exposure time you can calculate the total radiation dose in a specified period.

According to the Scientific Committee of the United Nations on the Effects of Atomic Radiation (UNSCEAR), the effects of radioactivity on humans per radiation dose are as follows:

  • <10 mSv: There is no direct evidence for health effects
  • 10-1000 mSv: No direct impact, increased incidence of certain types of cancer in exposed populations at higher doses
  • 1000-10000 mSv: Nausea, vomiting (radiation sickness), probability of death, increased incidence of certain types of cancer in exposed populations
  • > 10000 mSv: Death

Examples of radiation doses:

  • 10-hour flight by plane: 0,03 mSv
  • Chest X-ray: 0,05 mSv
  • CT: 10 mSv
  • Radon (annual report): 0,2-10 mSv (average 1,26 mSv)
  • Subsoil (annual report): 0,3-1 mSv (average 0,48 mSv)
  • Food (annual report): 0,2-1 mSv (average 0,29 mSv)
  • Cosmic radiation (annual report): 0,3-1 mSv (average 0,39 mSv)
  • Total annual radiation exposure from the natural environment: 1-13 mSv (average 2,4 mSv)

Obviously, conventional medical applications (radiography, computed tomography, scintigraphy, etc.) can considerably increase the annual radiation dose received.

Especially during pregnancy, some official scinetific bodies like the Greek Atomic Energy Commission (GAEC), which is the national regulatory authority in the field of radiation safety and nuclear safety, proposes to seek alternative diagnostic methods or therapies with zero or lower radiation exposure of the fetus.

What are the health effects of radioactive radon gas?

radonhomeRadon is a radioactive gas which comes from the decay of uranium found in the earth's crust and is still the major source of human exposure to radioactivity.

Radon is released from the soil and enters buildings by pipes and cracks and especially accumulates in low floors with inadequate ventilation. The current practice of using air-tight doors and windows, doors and other building materials for thermal insulation purposes, increases the concentration of radon in modern homes.

Many areas have elevated levels due subsoil radon.

Elevated radon values recorded and near high or medium voltage cables. Research at the University of Bristol showed that the presence of high levels of low-frequency radiation increases up to 18 times the accumulation of radon particles in space [15].

highvoltageradonradiation

Radon is used therapeutically in dozens of spas or radon caves or thermal springs around the world, where patients are exposed to very high concentrations of radon for a limited time. However, long-term exposure to higher than normal levels, as a result of the entry of radon from cracks and pipes in homes and accumulation in long hours of use areas, is a possible damaging factor for humans.

Radon has been added to list of the proven carcinogens (Group 1 human carcinogen) by the International Agency for Research on Cancer (IARC - International Agency for Research on Cancer) since 1988 and according to the World Health Organization [16]:

  • Radon is, after smoking, the second most important cause of lung cancer in many countries.
  • Causes of between 3% and 14% of all lung cancers.
  • It is the leading cause of lung cancer in non-smokers.
  • The lower the concentration of radon in a home, the lower the risk.
  • There is no threshold below which radon exposures carries no risk.
  • The likelihood of lung cancer increases by 16% for each 100 Bq / m3 increase in the concentration of radon!

In the European Union, lung cancer is the most common cause (about 20%) of cancer death [17].

Based on epidemiological investigations in nine EU countries it was estimated that approximately 9% of deaths from lung cancer may be due to exposure to radon in the home.

How we measure radon, what are the safe levels of exposure and how do I reduce radon levels in my space?

The measurement radioactive radon gas is made with digital radon meters or detectors or dosimeters (alpha particle meters) which record the radon concentration per cubic meter (in Bq / m3). Becquerel (Bq) is the number of radioactive disintegrations per second. Other radon measurment unit used is the pCi / lt (pico-curies per liter), where 37 Bq / m3 = 1 pCi / lt.

The average radon concentration values differ from region to region and are higher indoors eg in USA the average values are 15 Bq / m3 outdoors and 50 Bq / m3 indoors [18].

Some officially recommended limits for exposure to radon are:

  • European Union [19] (proposed for existing buildings): 400 Bq / m3
  • European Union (recommended for new buildings): 200 Bq / m3
  • US Environmental Protection Agency (EPA): 150 Bq / m3
  • German Institute for Building Biology (IBN = Institut für Baubiologie + Ökologie Neubeuern): patient <30 Bq / m3, very strong> 200 Bq / m3

Ways to reduce elevated radon values:

1.Increase ventilation by opening windows

2.Locate the cracks in walls, pipes and floors and seal them

3.If you are in the construction phase you can add special sealing membranes or create vacuum or special subfloor beneath the basement floor

What are the health effects of nuclear accidents?

Near the nuclear accident areas exposure to very high levels of radiation can cause nausea and vomiting, cataracts, sterility, hair loss and in some cases death [20], [21].

High levels of radioactivity due to an accident can be maintained in an area for years.

Radioisotopes released in nuclear accidents pollute the air and end up in vegetables and drinking water and from there to the animals, milk and humans.

Nuclear accidents releas into the atmosphere radioactive elements with short half-times, which emitt more radiation in a shorter period and affect more the cells of specific organs (eg radioactive iodine-131, cesium-137, strontium-90, etc.) .

However, estimates of scientists about the effects on health from various nuclear accidents are quite different, with the most important example beeing the nuclear accident at Chernobyl in 1986 [22]. Some scientists argue that the accident caused a large increase in cancers (especially thyroid leukemias), genetic deformities and early childhood mortality and considers the associated deaths approaching one million, a figure that will continually grow [23].

On the other hand, the Scientific Committee of the United Nations on the Effects of Atomic Energy (UNSCEAR) in a recent review scientific data claims that, apart from the 57 deaths that resulted from the initial explosion, the radioactive leak lead to only 4000 cases of thyroid cancer [24]. Note that the lack of iodine in the diet of the inhabitants of these areas has been an additional factor in development of thyroid cancer. [25] Also, in evacuation areas, unemployment and financial problems that followed the accident affected psychologically large population serving, which itself had a negative health effects.

How large is nuclear accident of Fukushima compared to that of Chernobyl?

In the scale of risk of nuclear accidents, the accident at Chernobyl, which was considered the biggest so far, was Grade 7. The accident in Fukushima and initially characterized degree 4, was upgraded to grade 7 (communication of the International Agency for Nuclear Energy on April 12, 2011 [26]).

In Chernobyl an explosion had occurred and the smoke from the fire was carrying large amounts of radioactive material for about 10 days across Europe, significantly contaminating water and food.

In Fukushimathe air pollution is gradual which can exceed a total that of Chernobyl, since there are far more nuclear fuel (1760 tonnes compared with only 180) and the radioactive leak can continue for decades [27].The major leak of radioactivity at present is to the sea polluting fish and seaweed.

There is a risk for remote countries because of radiation leakage from nuclear reactors in Japan?

For remote countries the problem is not so much the increase in radioactivity in the atmosphere, but the increased consumption of radioactive elements through the food chain.

The French Committee for Research and Information on Radioactivity (CRIIRAD), which measures the levels of radioactive elements in a report says that certain foods is logical to avoid especially by children and pregnant women, as that can not be predicted how long the radioactive contamination of the food chain will continue.

Ways of reducing exposure to radiation from nuclear accident

  • Avoid consumption of vegetables, meat, fish and milk from the affected radiation areas.
  • The largest concentrations of radioisotopes present in leafy vegetables (eg lettuce, spinach, cabbage, etc.), except those produced in greenhouses.
  • Wash vegetables before consumption (although the French Committee for Research and Information on Radioactivity claims that this practice is not very effective).
  • Also radioisotopes are concentrated particularly in the milk, cream and cheese from grazing animals out and feed on grasses (most burdened sheep).
  • Use water filter (eg coal) for the water you drink.
  • Taking potassium iodide is only recommended before or just after exposure to high levels of radioactivity. Iodine only protects the thyroid, preventing the absorption of radioactive iodine.
  • Do not start taking iodine just in case, because this can also have negative effects on health. Be sure to cover the daily needs of iodine through food (natural sources of iodine: seafood, cheese, etc.). For someone who has a lack of iodine in the diet it may make sense taking seaweed supplements (eg Kelp) which contain iodine but at lower dosages.
  • Possible protection might offer vitamin supplements and minerals that contain amounts of non-radioactive forms of cesium and strontium.
  • Other supplements recommended are NAC (N-Acetyl-Cysteine), chlorela, spirulina, pectin etc.
  • Stay indoors with windows closed or using a special mask to filter radioactive particles if you live near the accident area.

Is radioactivity always harmful?

As explained above, the effects on human health from every form of radiation depend on many factors such as type of radiation, the active radiation dose, the effective dose rate, the exposure time, whether the exposure is internal or external but also the time decay of each radioactive element.

Since man was always exposed to ionizing radiation from the natural radioactive environment , the human organism has developed some adaptation mechanisms to adapt.

As mentioned by the Scientific Committee of the United Nations for the Effects of Atomic Radiation (UNSCEAR) "The radiation damage will usually be repaired by these normal cell repair processes".

Some scientists claim that damage to the cells caused by ionizing radiation, when it occures in a controlled fashion, can enhance the body, just as it happens during physical exercise. It is no coincidence that exposure to certain types of radioactivity, was deliberately used for centuries for therapeutic purposes.

Radiation Hormesis = a little radiation is good!

Supporters of the hormesis theory, argue that radioactivity may have health boosting effect. According to the Hormesis theory (from the Greek word Horme = rapid motion), the negative effects of toxic substances, radiation etc. are not linearly proportional to the levels of exposure. Specific doses are beneficial for the body as they cause the stimulation of all the body's systems for the repair of temporary damage. Specifically, periodic exposure to small or medium doses of radioactivity (Radiation hormesis):

  • Causes controlled DNA damage that stimulates the immune system and repair mechanisms of genetic material [29].
  • Regenerates cells, activates important enzymes aiding in the regulation of stress and suppresses cancer, hypertension and diabetes [30].
  • Is an exercise for the immune system. "It's like doing push ups" says nuclear engineering professor at the University of Massachusetts Gilbert Brown [31].
  • It dramatically improves the survival rates of animals exposed to high levels of radiation [32]. Similarly, residents of naturally radioactive areas have half chromosomal aberrations than others when they receive a high radiation dose [33].
  • It is essential for the normal functioning of the body, such as vitamins and minerals, according to researcher Dr. Luckey [34]. He believes that modern man with the little contact with the sun and nature suffers from lack of radioactivity.
  • It was widespread in the early 20th century in the medical community. The American Medical Association had promoted the use of radioactive radium in various treatments. Radium water was sold as elixir for health [35].
  • It is used to treat various symptoms by placing radioactive rocks in various parts of the body (also sold online [36]!).
  • It is used as an alternative treatment for cancer, when applied to the whole body. It has an enhancing effect to the body [37], in contrast to the higher intensity ionizing radiation used topically in conventional radiotherapy which have many side effects.
  • It is used to treat arthritis [38], asthma [39] and a multitude of other diseases [40] in dozens radon spas and radon thermal springs worldwide.
  • Radioactivity levels in the healing radon spas can be very elevated - eg in Montana, USA It is 400 times greater than the recommended limit by the US Environmental Protection Agency (EPA) [41]!

Does only ionizing radiation affect health?

The usual separation of electromagnetic radiation and non-ionizing, creates the false impression that the only biologically harmful process is ionization and that non-ionizing electromagnetic radiation from power supply, mobile phone antennas, cordless phones, WiFi, etc. is not harmful.

However, unlike radioactive ionizing radiations which has always existed in the evolution of mankind, non-ionizing radiation is mostly artificial and recently introduced on the environment, and according to scientists even very low levels of exposure to non-ionizing radiation may in the long term cause significant health effects through several biological mechanisms other than ionization.
