Mobile phones

  • Remove the cell phone from your head during calls using speakerphone or cable hands-free.
  • Do not carry the phone in your pocket when you talk, as the genitals are particularly sensitive to wireless radiation.
  • Limit your talk time from using it when it is really necessary - better contact by sending SMS.
  • Prefer fixed telephone lines, especially when making long calls.
  • Prefer to make calls when you have 3G signal as the emitted radiation is much less than when you have 2G signal.
  • Avoid using the phone in areas with bad signal, because the phone will be transmitting at full power in order 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 will be recycled internally reflected on metal surfaces, but also, as you move the mobile phone transmits at full power trying to connect to the nearest antenna.
  • Using bluetooth headset is not recommended since it is a weak but permanent radiation source (exception: when you talk too much on the cell phone, especially in areas with poor signal, it is preferable to keep your phone and bluetooth headset away and peak up your bluetooth headset when you have a call).
  • Divide your talktime holding the cell phone on both sides of the head.
  • If you use a smartphone, turn on the downloadable data via Wi-Fi or the mobile network, only when you want to browse the Internet. Most applications, download data whenever then can significantly increasing the radiation emitted by your cell phone.

Cell phone masts

  • Mobile phone antennas (base stations) radiate continuously.
  • They are usually installed on rooftops in the residential and commercial buildings or on hills (especially next to busy roads)
  • There are everywhere - the most densely populated area, the more cell phone masts.
  • They affect most the areas that have visual contact with the antennas.
  • Cell phone masts are often camouflaged as heaters, billboards, chimneys etc.

mobilephonemastscamouflaged

If your phone has low signal in your house, it means that your provider does not have an antenna near you or their signal does not reach you. However there may a cell phone mast near you from other providers.

  • You can see if you exceed the recommended safety limits due to the cell phone masts in your area (visible or not) by using a High Frequency Radiation Meter.
  • Identifying the radiation hotspots will help you move your bed, your sofa and your desk away.
  • Electromagnetic shielding materials that reflect more than 99% of wireless radiation offer simple solutions for protection from wireless radiation.
  • Since windows are the most vulnerable points of penetration from external wireless radiation, the largest decrease in radiation due to cell phone masts can be achieved by placing adhesive film or curtain shield in the windows of the building (especially those facing the antenna). 

WINDOW SHIELDING

  • The walls of the building reflect/absorb a portion of the external wireless radiation depending on the thickness and type of structural materials. Shielding the walls and ceilings internally or externally with electromagnetic shielding paint or stainless steel mesh can achieve an even greater reduction of radiation in the areas. 

PAINT SHIELDING

  • Practical solution, at least for the sleeping areas, offer the electromagnetic shielding canopies which do not allow the penetration of radiation from most directions, ensuring minimal disturbance of your sleep by current and future wireless radiation sources.

Wireless Internet (WI-FI or WLAN)

  • dreamstime 17058607The wireless modem-router you use to connect to the Internet constantly radiates, whether you are using it to surf the internet or not.
  • Turn off the wireless function of your wireless router modem (usually by pressing a button - or through its online setting - ask the manufacturer if you do not know how) and use a network cable (ethernet) to connect your computer or laptop.
  • If you do not want to disable the wireless function of the modem, move it as far away from places where you spend much of your time and shut down the modem when you are nto using it or at least during the evenings.
  • Alternatively you can use Power Line adaptors (insert an adapter Powerline into an outlet and connect it to the modem and other adapters in sockets of remote rooms. where you want to have internet connection).

Cordless phones

  • The handset of the cordless telephone only radiates when you speak while the base of the cordless phone radiates constantly, even on stand by. sign for cordless phones with zero radiaiton in stand by.
  • ECO DECT ZEROReplace your cordless telephone with a wired one or at least a wireless phone with zero radiation on stand by mode, the base of which emits radiation only when you make calls.
  • If you do not want to replace the cordless phone, place it as far away from places where most of your time (especially the bedroom).
  • During calls switch on the speakerphone, and place the headset as far away as possible from your body.

What to do about the wireless devices (cordless phones, routers, etc.) of your neighbors

  • Since most houses now have cordless telephones, Wi-Fi modems or other wireless antennas such as baby monitors, cell phone signal repeaters, wireless game consoles, smart TVs etc you are likely to be exposed to high levels of wireless radiation because of your neighbors.

You might not use wireless devices and speak very little on your cell phone and still be exposed to cumulative higher radiation levels than heavy users of cell phones, due to your exposure to radiation from antennas of neighboring apartments.

  • You can see how much wireless radiation is coming from neighboring apartments by using a High Frequency Radiation Meter.
  • In case of high radiation values ​​because of your neighbors, you can move your bed, desk or sofa away from wireless hotspots.
  • Fabrics reflecting wireless radiation can be placed in the living room or your bed when the radiation source is located below.
  • With special electromagnetic shielding paint you can paint the walls from which the wireless radiation comes from. 

FABRIC 1

  • Practical solution, at least for bedrooms, offer the electromagnetic shielding canopies, which are especially useful in buildings with dozens of wireless phones and Wi-Fi networks.

Electrical devices

  • Distance the high usage areas of your house (eg bed, sofa, desk) from:
  • high consumption appliances such as kitchen, electric heaters, floor heating, boilers, etc.
  • low voltage devices such as chargers, transformers, electric clocks, laptop, printers, lamps 12V etc.
  • appliances with electric motors, such as the refrigerator
  • electricity meter and electric panel
  • photovoltaic system charger, generator, inverter
  • boiler and other electromechanical installations

Electrical appliances such as shavers, the hair dryers, blenders, vacuum cleaners etc. usually produce high magnetic fields. However, because their use is usually of short duration, we do not think that they can cause residual biological effects (with the possible exception of people with electrohypersensitivity). 

  • fluorescentLimit the use of nonlinear load electronic devices which distort the mains signal: fluorescent and enrgy saving lamps, AC adapters, dimmer switches with electronic volume control etc.
  • Avoid using fluorescent lamps and energy saving lamps in areas where you spend most of your time. Use them only in corridors and outdoors.
  • LED bulbs emit lower radiation, though there are concerns for their safety due to their brighter light.
  • Safer choices are incandescent lamps (if you can still find them on the market) and many types of halogen lamps (regular voltage - not low voltage).
  • Keep electrical appliances as far away from the bed of your bedroom, especially if they are not grounded (their plug does not connect to the earthing pin of the power outlet).
  • Avoid using electric blankets or water beds or at least disconnect them from the electrical outlet before going to bed.
  • New technology flat screens (LCD) emit lower levels of radiation than the older type (CRT etc.). In any case, avoid sitting in their immediate vicinity.
  • Measure the radiation emitted by all your electrical appliances and avoid the radiation hotspots by using a Low Frequency Radiation Meter.

Laptops - tablets

  • laptopUsing a laptop / tablet is an important source of electromagnetic fields exposure for a large portion of the population.
  • Due to their close contact with our body they expose us to elevated low frequency electric and magnetic fields due to their battery, cables and electrical circuits and high frequency fields due to their WLAN or WIFI antennas which connect wirelessly to the internet.
  • There is research linking using laptop with DNA damage and degradation of reproductive capacity.
  • You can distance the laptop from your body with the help of an external wired keypad.
  • By placing the laptop to a laptop stand, the screen is lifted to an ergonomically correct height which helps you avoid future problems in the neck.
  • Turn off the wireless function of the laptop / tablet when you are not wirelessly surfing the internet.
  • Better use a wired internet connection using an ethernet network cable to connect your laptop to the modem
  • Alternatively use powerline adaptors which pass the internet signal through your homes electrical circuits. This technology, however, is not the ideal substitute to networking with ethernet cable because adding a high frequency signal to the electric network of the house is distorting the mains electricity signal (maybe a problem in homes with elevated low frequency electric fields).
  • Ethernet cables or powerline adapters can also be used with some tablets by using Ethernet to USB or mini USB adapters.
  • Laptops may emit elevated low frequency electric fields depending on their grounded or not plug, network cable connection etc. - only a measurement of electric fields can tell us the safest way to use the laptop.
  • Reduction of the electromagnetic fields exposing your genitals when you have your laptop or tablet WiFi antennas enabled is feasible by using electromagnetic shielding materials that reflect more than 99% of wireless radiation: Defenderpad (www.defenderpad.com), Belly Armour (www.bellyarmor.com), Naturell fabric etc.

Electrical cables

  • The electrical cables that are build in your walls produce low frequency electric fields 24 hours a day low freqeuncy magnetic fields when there is current flow (when you turn on the lights, operate electrical appliances, etc.).
  • The exact location of the cables is usually not obvious but can be detecting by using a low frequency field meter.
  • Missing earth connection or faults in cable insulation often give high measurements of low frequency electric fields.
  • High magnetic fields are often created due to incorrect electrical connections (eg connecting the neutral conductors from different circuits) which are also a risk to fire or electric shock.

Power lines, transformers, substations etc

  • high voltageHigh voltage transmission lines (100-500 kVolt) go through many populated areas and are connected to the more dense medium and low voltage power distribution lines (110/230/400 Volt - 50 kVolt)
  • To reduce the voltage from high to medium voltage lines and medium to low voltage lines we use voltage transformers (substations)
  • The electric fields emitted by cables and substations usually affect only outdoors areas since they are blocked by most building materials. In underground distribution lines, electric fields are always grounded.
  • However, magnetic fields emitted by cables penetrate almost all building materials.

According to statistics the most common causes of elevated magnetic fields are low voltage power lines which are everywhere and not the high voltage lines!

  • The values ​​of the magnetic fields that power lines emit are not easy to predict since they depend on many factors such as power consumption, the provision of electricity conductors, the connections of the local distribution network etc.
  • The flickering TV or computer screen is a possible indication of the presence of very high values ​​of magnetic fields.
  • You can find out whether your house is exposed to high electric or magnetic fields by using a Low Frequency Radiation Meter.

Shielding solutions for wireless radiation

Electromagnetic shielding solutions minimize the penetration of artificial high frequency radiation and is recommended especially for bedrooms, because electromagnetic interference is considered more aggravating during the critical hours of sleep.

Shielding solutions also protect against any future presence of new radiation sources (eg new cell towers, new neighbors wireless devices, new radio stations and amateur radio antennas, WI-MAX networks, private security, transport companies and taxi networks, smart meters, radars and a variety of other wireless applications).

The all-round shielding of an area, that protects against the penetration of wireless radiation from all directions, is achieved by painting the walls and ceilings internally or externally with electromagnetic shielding paint and placing shielding film or curtain on windows.

Practical solution for the bedrooms offer the electromagnetic shielding canopies. The do not allow radiation penetration from all directions (except from the bottom of the bed - but there are shielding fabrics or gauges for positioning under the mattress or on your bed).

Wireless Free Ζones in houses, hospitals and hotels? How to create them

Why are areas with zero wireless radiation are necessary to a part of the population? Which countries are developing Wireless Free Zones in hospitals, hotels and shelters? How to create an area without radiation in your home or office space?


wirelessfreezones 

“(governments should) designate wireless-free zones in cities, in public buildings (schools, hospitals, residential areas) and, on public transit, to permit access by persons who are hypersensitive to EMF.” Benevento Resolution, International Commission for Electromagnetic Safety [1]

“(congress should) establish cell phone and wireless-free neighborhoods, transportation options, government buildings, and public spaces; require employers to establish wireless free zones; and, mandate the removal of cellular and wireless technologies from public schools and their properties.” ElectromagneticHealth.org petition to the American Congress [2]

How to shield from electromagnetic pollution

The shielding of an area is achieved by painting the walls and ceilings internally or externally with electromagnetic shielding paint and placing electromagnetic shielding window films or curtains in the windows.

Externally, you can use stainless steel mesh.

Practical solution for the bedrooms are the shielded bed canopies. They inhibit penetrating radiation from all directions except from the bottom of the bed (but you can put shielding fabric underneath the bed).

 Electromagnetically shielding the areas where you spend most hours of your day:

  • gives the body the necessary daily break from continuous exposure to electrosmog
  • helps you avoid health problems form long-term exposure limits to radiation
  • protects you form existing and future wireless radiation sources
  • minimizes the penetration of wireless radiation from all directions

“A major contemporary threat to the health of Society is man-made ‘electrosmog’. This non-ionising electromagnetic pollution of technological origin is particularly insidious, in that it escapes detection by the senses – a circumstance that, in general, tends to promote a rather cavalier attitude, particularly with respect to the necessity of ensuring an adequate degree of personal protection. Yet the nature of the pollution is such that there is literally ‘nowhere to hide”. Dr. Gerard Hyland, Biophysics, University of Warwick, 2 times Nobel Prize contender Medicine [3]

Great increase of wireless radiation levels in recent years

The current unprecedented levels of high frequency wireless radiation are constantly increasing due to the proliferation of existing sources and the continuous addition of new wireless applications.

Even if you avoid putting wireless devices in your house, you will be more or less exposed to a mixture of high-frequency radiation from:

  • mobile antennas
  • broadcasting antennas
  • amateur radio antennas
  • wireless modem-router (WI-FI), cordless phones, Baby Monitors, wireless game consoles, wireless alarm systems, fire detection and control temperature
  • military radar, airports, ports, meteorological services etc.
  • radio networks fo police, private security companies, transport companies, taxi etc.
  • WIMAX networks (long range wi-fi)
  • antennas for ministries, embassies, diplomatic missions, the Armed Forces, the Security Forces and Coast Guard, Civil Aviation Authority, etc.
  • smart meters
  • many other wireless applications

"Thus in the frequency range 100 kHz to 300 GHz, 50 years ago it was scarcely possible to measure 10 pW/cm2 on the ground in our countries. Today, depending on the location, values one million to one thousand million times higher are recorded because of the explosion of telecommunications. European Parliament Resolution B3-0280/92 [4]

Shielding your area is highly recommended:

  • if you have optical contact with cell phone masts or other obvious sources of radio radiation
  • in densely populated areas, especially on the higher floors of buildings
  • in apartment buildings because of the presence of a multitude of wireless phones and wireless Internet networks
  • in bedrooms because artificial electromagnetic interference is considered more aggravating the critical hours of sleep

WIRELESSFREEBUILDINGSWireless Free Zones in hospitals, spa and hotels

  • Upgrade your services and differentiate from the competition by offering areas isolated from electromagnetic pollution, which are essential for a growing proportion of the population.
  • Wireless free zones have already been created in hospitals in Sweden [5] to treat sensitive to electromagnetic radiation patients
  • Locations in France (Drôme) and Italy (Vena del Gesso) have been declared shelters for people sensitive to radiation [6].
  • Cities such as Slocan Valley Canada, create respective zones to attract new residents and tourists [7]

EHSRefugeZone

Other applications of electromagnetic shielding:

  • protection of sensitive to electromagnetic interference equipment in laboratories, hospitals, diagnostic centers, recording studios, etc.
  • creation of Faraday cage, which is the only measure of protection for electronic devices, cars, etc. during solar storms (have occurred in recent history, causing heavy damage)
  • preventing data theft from corporate buildings, military installations, etc.

Electromagnetic shielding = Health protection

  • Research relates wireless radiation with health effects such as brain cancer, testis, skin, salivary gland, insomnia, depression, male infertility, miscarriages pregnancy, leukemia, etc.
  • World Health Organization (WHO) has listed wireless radiation as "possibly carcinogenic".
  • Pregnant women, children, sick and elderly are considered to be the most vulnerable groups.
  • A growing portion of the population has allergic symptoms at very low exposure levels ("electrohypersensitivity")

"Scientific studies at the cellular level, whole animal level and involving human populations, shows compelling and comprehensive evidence that RF/MW exposure down to very low residential exposure levels, levels which are a minute fraction of present “safety standards”, results in altered brain function, sleep disruption, depression, chronic fatigue, headache, impaired memory and learning, adverse reproductive outcomes including miscarriage, still birth, cot death, prematurely and birth deformities. Many other adverse health effects have been found, predominantly cancer of many organs, especially brain cancer, leukemia, breast cancer and testicular cancer. Studies have also found that RF/MW exposed parents have more children with CNS cancers and other health defects. These effects are consistent with genetic damage caused by RF/MW" Dr. Neil Cherry, Lincoln University in New Zealand [4]

Electromagnetic shielding = Better sleep quality

  • Artificial electromagnetic interference is considered more aggravating during the critical hours of rest.
  • Research indicates that wireless radiation delays sleep and decreases the duration of the deep sleep (REM).
  • At least 3 epidemiological studies have already linked the nearby presence of cell phone masts with sleep problems and depression in the neighboring population.
  • People with insomnia problems have decreased immune response, increased levels of stress hormones, increased susceptibility of cancer, heart attack, diabetes etc.

Electromagnetic shielding = Protection from electrohypersensitivity

  • stress17The rapid growth of wireless electromagnetic fields in the cities has been linked to the development of a range of symptoms in a portion of the population, a phenomenon called electrohypersensitivity.
  • The symptoms that occur in some even at very low levels of radiation include: nausea, headaches and migraines, ringing in the ears, pain in bones and muscles, numbness in the face, dry eyes, inability to concentrate, unexplained fatigue, tachycardia, rashes, dryness throat and oral cavity, sinuses swelling etc.
  • Researchers Hallberg and Oberfeld studying the growth rates of the disease, predicted that by 2017, 50% of the population will display allergic reactions to artificial radiation [8]
  • The effect on the lives of people affected is often dramatic, as it is difficult to work and move in public places because of excessive presence of artificial radiation.
  • Electrohypersensitivity is already recognized as a disability in Sweden, where it is considered that it affects 3% of the population (approximately 250,000 people). Great Britain and Canada are moving in the same direction.

More about "the allergy of the 21st Century"..

“Sensitivity to electromagnetic radiation is the emerging health problem of the 21st century. It is imperative health practitioners, governments, schools and parents learn more about it. The human health stakes are significant” Dr. William Rea, former president of the American Academy of Environmental Medicine [9]

"Sensitivity to EMF has been given the general name “Electromagnetic Hypersensitivity” or EHS. It comprises nervous system symptoms like headache, fatigue, stress, sleep disturbances, skin symptoms like prickling, burning sensations and rashes, pain and ache in muscles and many other health problems. Whatever its cause, EHS is a real and sometimes a disabling problem for the affected persons. Their EMF exposure is generally several orders of magnitude under the limits of internationally accepted standards." World Health Organization [10]

"The European Parliament (…) calls on Member States to follow the example of Sweden and to recognise persons that suffer from electrohypersensitivity as being disabled so as to grant them adequate protection as well as equal opportunities.” European Parliament resolution on the health problems associated with electromagnetic fields (2008/2211) [11]

How to shield your house from electromagnetic radiation

Protect yourself from the electromagnetic fields of cell phone masts, WiFi networks, etc. with innovative shielding materials. How to use special reflective paints, window films, fabrics, canopies, curtains and meshes.


ELECTROMAGNETICSHIELDING

How to measure the radiation levels in my space to see if there a reason to shield?

You can measure the radiation levels in your spaces using a high frequency radiation meter and a low frequency radiation meter.

How to shield a space from the radiation of cell phone masts, wireless Internet networks (wi-fi), cordless phones, etc .;

Wireless radiation enters the building easily from windows (unless the glasses have a metal coating) and are blocked to some extent by the walls depending on the thickness and type of structural material.

Electromagnetic shielding materials are special fabrics, window films, meshes, wallpapers and paints that reflect more than 99% of wireless radiation due to their special conductive composition.

  • Window films with metal coating or curtains with special weave of copper and silver, are placed on the windows, significantly reducing the levels of radiation due to external radiation sources (eg cell phone masts), since the windows are the most vulnerable points to the penetration of wireless radiation.

radiationshieldingcurtains

  • The walls of buildings reflect/absorb a portion of the external wireless radiation, depending on the thickness and type of the structural material. By painting the walls with electromagnetic shielding paint, we can achieve even greater reduction of radiation in a space, which is usually desirable when there is a source nearby (eg cell phone masts at distance <200 m). The paint can even be used even on the floor. These paints provide higher radiation attenuation rates, even for very high frequency radiation, while also shielding from the low-frequency electric fields (e.g. from wires, electrical appliances, etc.).

raditionshieldingpaint

  • On walls that are have not yet been plastered or on floors that have not been laid, you can place a special stainless steel mesh. This mesh is stainless steel so it can be easily used outdoors (eg nailing it on the external walls).
  • Electromagnetic shielding fabric which reflects wireless radiation can be placed underneath the sofa or bed when the radiation source is below (eg wireless modem from neighbor).
  • Practical solution for the bedrooms offer the shielded bed canopies. They inhibit penetrating radiation from all directions except from the bottom of the bed (but you can put shielding fabric underneath the bed). With such canopies, you get the minimum disturbance of your sleep from your current and future wireless radiation sources and do a daily break from electromagnetic pollution. 

radiationshieldigncanopies

The actual radiation attenuation rate depends on the reflection provided by each material but also on the coverage of the surfaces. Any unshielded spot is a potential point of penetration that can reduce the local or overall result of the shielding project.

The use of main shielding materials which provide shielding rates 20-40dB (paint, window films, curtains, canopies and mesh) at over 50% of the areas surfaces usually means practical reduction of radiation values of more than 90%. For higher shielding rates> 99%, which are usually desired when recording values> 10,000 microwatts / m2, we recommend the use of materials that provide attenuation> 50dB (special wallpapers, canopies and curtains), or a combination of materials (eg .g. curtain and window film) and greater emphasis on prevention unshielded openings.

For shielding from external radiation sources the greatest reduction is achieved by shielding the windows, walls and roofs facing the source. Shielding and other sides of space, we also reduce the radiation penetration through reflections. Shielding all sides constitutes a preventive measure of protection from the possibility of the future presence of new sources of radiation.

Electromagnetic shielding solutions are especially recommended in bedrooms, because the artificial electromagnetic interference is considered more aggravating during the critical hours of sleep.

Common metal meshes, due to their large hole opening, provide low rate of screening, especially at high frequencies. Also, materials such as aluminum foil are not suitable for use as shielding materials because they are not breathable, often retain moisture (causing mold in walls) and are oxidized with time.

Where are high frequency electromagnetic shielding solutions usually applied?

  • In houses adjoining cell phone masts, radio broadcasting antennas etc. (Most burdened are rooms with windows that have visual contact with the antenna).
  • In apartment buildings due to the presence of a multitude of cordless phones and wireless Internet networks.
  • In densely populated areas because of the presence of more cell phone masts.
  • On the upper floors of buildings, which are more exposed to all kinds of wireless radiation than the ground floor or basement areas.
  • In schools, nurseries, maternity wards, hospitals, nursing homes, etc. due to the greater sensitivity of children, fetuses, pregnant women, sick and elderly in wireless radiation.
  • In hotels, Spa, medical centers, clinics, etc. which want to create zero wireless radiation zones.
  • In office buildings with high surrounding usage of wireless devices.
  • In houses made of wood or with thin walls, in which the wireless radiations penetrate easily.

Shielding materials are the only solution to protect against the continuous increase of electromagnetic pollution from cell phone masts, broadcasting antennas, wireless Internet networks (WI-FI), cordless telephones, satellites, radar, WI-MAX networks (wide range WI-FI), antennasa of ministries, embassies, army, amateur radio antennas, police, private security companies, transport companies and taxi communication networks, smart meters and a variety of other wireless applications.

How to shield a space from the radiation of high voltage lines, transformers, electrical panels, etc?

These sources generate magnetic fields due to the leakage of current and electric fields due to the presence of voltage.

Shielding of magnetic fields

Magnetic fields penetrate most materials unaffected.

Magnetic shielding materials have very high permeability and "pull" the magnetic field lines forcing them to pass through them, thus reducing the magnetic field values in the rest of the space. They are also very expensive.

Materials such as copper, lead or aluminum are not suitable for shielding the magnetic fields as many people believe, because they have very low permeability (relative permeability ~ 1). Magnetic shielding materials are metal alloys, ceramics etc. with a much higher permeability (relative permeability> 2000).

In rooms that have windows, the shielding of windows is usually required to achieve a significant reduction. Alternatively, you can create specific structures that cover only certain areas (eg workstation, bed etc.).

Due to cost and effectiveness constraints their use is only recommended in cases of very high radiation values when it is not possible to distance yourself from the source.

The protection from small transformers, motors and electrical panels is relatively easier because you can shield the source instead of the entire room.

Shielding of electric fields

The lines of the electric fields are directed from higher to lower volotage points and are attracted to grounded conductive materials.

Thus, the electric fields due to high voltage lines do not usually affect at all the interiors of neighboring buildings as they are grounded by most building materials (possible exception: wooden houses).

However, in outdoor areas close to high voltage lines, electric fields may be high. The electric fields can be reduced by placing trees or other grounded conductive objects (eg mesh stainless steel) facing high voltage power lines.

Indoor electric fields which are due to electrical devices, building electrical installation cables, electrical panels etc.. A convenient solution for their shielding electrical fields is to use conductive paint or conductive bed canopies which are grounded and pull the electric fields.

3) What is the cage Faraday, how I can construct it?

Faraday cage is called each conductive shell that covers all surfaces of an area and shields most types of artificial electromagnetic radiation (exception: low frequency magnetic fields).

To create a a faraday cage you cover every surface of a room with grounded shielding materials (paint, mesh etc).

The conductive shielding bed canopies are an easy solution to create a Faraday cage in the bed area.

The creation of a Faraday cage is used for:

  • protecting sensitive to electromagnetic interference electronic equipment in laboratories, hospitals, diagnostic centers, recording studios, etc.
  • avoiding wireless data theft from corporate buildings, military installations, etc.
  • maintaining the functionality of electrical appliances, cars, etc. during solar or geomagnetic storm (have occurred in recent history, causing major damage and are considered likely to occur in the near future ) or due to emitting EMP (Electromagnetic Pulse) in case of war with electromagnetic or nuclear weapons (a popular theory mainly in the USA)
