Do you know how many RF radiation emitting antennas surround you today?

You are exposed daily to an invisible electromagnetic smog from dozens visible and non visible transmitting antennas: tv and radio broadcasting antennas, radars, cell phone masts, wi-fi wireless networks, cordless phones etc. How to find out which sources affect you.

What is high-frequency radiation

High frequency radiation is generated from wireless transmitters (antennas, radars, etc.) which are used in wireless telecommunications, broadcasting and dozens of other applications.

Their emission frequencies are usually from 0,1 - 10GHz (billion hertz), which are much higher than the low-frequency radiation from wired sources such as cables and transformers (AC frequency = 50-60 Hz).

Antennas usually emit continuously and may circulate freely at distances of a few meters to several kilometers.

Today it is hard to find areas unexposed to wireless radiation.

Are there health effects?

High frequency radiation has been linked to insomnia, depression, brain cancer, testis, skin, salivary gland, male infertility, miscarriages pregnancy, leukemia, etc.

In May 2011, the World Health Organization (WHO) announced that  wireless radiation is possibly carcinogenic.

"Scientific studies at the cellular level, whole animal level and involving human populations, shows compelling and comprehensive evidence that RF/MW (radio frequency/microwave) 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 [1]

High Frequency Radiation Sources

Mobile phones

Your mobile phone mainly emits pulsed radio frequency radiation 900-2500MHz while talking.

The research for health effects is contradictory, but cell phone use has been associated with damage to DNA, destruction of nerve cells, brain cancer etc.

Children are more vulnerable to the effects of radiation from mobile phones, because they have not fully developed immune systems and this is why many scientific organizations have warned against the use of mobile phones by minors.

Cell phone masts

Cell phone masts are placed in rooftops of buildings in every neighborhood and especially next to busy roads, in corporate buildings, factories, in densely populated areas with many offices, shops.

Most of the radiation is directed at residences located within 80-250 meters from the mast.

They are often camouflaged (like heaters, signs, chimneys etc) to avoid confrontations with the neighbors.

Surveys on the population residing in less than 300-400m. distance from mobile phone masts showed increased incidences of cancerinsomnia, headaches, nausea, inability to concentrate, memory loss, vision and hearing disorders.

TV and radio broadcasting antennas

Broadcasting antennas continuously emit relatively high power signals and research has linked proximity to them with childhood leukemia, brain cancer and melanoma (Merzenich [2], Ha [3], Hallberg [4] , Hocking [5]).

Many radio amateurs broadcast radio signals with a wide frequency range and power.

Television antennas in roof tops are usually only signal receivers and do not emit wireless radiation.

The higher floor of the house, the more exposed to radiation from radio and tv broadcasting antennas etc.

Cordless Telephones (DECT) and wireless internet (modem-routers-WiFi-WLAN)

The wireless internet routers and the bases of cordless phones are continuous wireless radiation emission antennas currently installed in most homes.

Their radiation has similar waveforms and frequencies but lower intensity than those of a cell phone mast.

However, being in closest proximity to our bodies, they often submit us to a greater amount of radiation than if we had a cell phone mast across the street.

The cordless headphone emits radiation only while talking.

Radars

The signal emitted from radars is strong pulses of high frequency electromagnetic wave (usually 2-10GHz) which scans the entire space, rotating 360 degrees by hitting each point within kilometers every few seconds (like a lighthouse).

They are usually situated at:

  • Airports
  • Harbors, marinas
  • Military airbases

Voice Picking technology

Voice Picking technology is mainly used in warehouses.

It consists of a central antenna that communicates with the antennas in the workers belts (typically at the frequency of 2,4 GHz, as the WLAN - WiFi).

You can reduce the radiation from the central antenna by moving it further away from the high use areas (but this way you might have signal reception problems).

The main problem for the workers is primarily the antenna located in their belts with which are in direct contact.

To reduce your exposure to radiation you can wear clothing that reflects wireless radiation.

Baby Monitors

It is unlikely that there is a wireless baby monitor with minimal radiation emissions, because very low transmission power would make it non functional.

The proposed safe exposure limits (<100mW / m2) are in most cases exceeded when there is a baby monitor in the same room.

In our opinion the wireless baby monitors can 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 are irreversible.

Smart meters - Smart Devices - Smart grid

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

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

Other wireless applications

Today's unprecedented wireless radiation levels are increasing, both in intensity and in a variety of electromagnetic signals by adding new wireless applications:

  • WIMAX (long range WIFI)
  • Antennas in ministries antennas, embassies, diplomatic missions, the Armed Forces, the Security Forces and Coast Guard, Civil Aviation Authority, etc.
  • Antennas for transfer data use within industrial plants, stadiums, building complexes etc.
  • Satellites
  • «Wireless ready» devices
  • Cordless keyboards
  • Devices that work with Bluetooth continuously activated
  • Wireless gamesconsoles
  • Interactive school boards
  • Wireless Speakers
  • Microwave ovens
  • Wireless alarm systems, fire detection and temperature control
  • Taxi communication (CB = Citizens Band)
  • Radio networks for police, private security companies, transport companies etc.
  • HAARP (= High Frequency Active Auroral Research Program)
