Electromagnetic Radiation(EMR/EMF) Knowledge

You are at step #1 in the "No Radiation For You 4 steps program"


"knowledge and understanding of radiation, its types and sources is very important".

Knowledge is the first step.

In this section of the site you will find knowledge about  EMF/EMR(Electromagnetic Fields/Electromagnetic Radiation), it's types, sources, its health effects, 

In these sub pages you will find also reference and links to other sources of information across the web and across the world about these subjects.

Non ionizing radiation

"Non ionizing radiation" is a General term that describe various types of radiation. Non-ionizing radiation as its it's name implies is electromagnetic radiation which is can not ionize the material (not taking electrons from their path around the atomic) through it passes.


EHS - Electromagnetic HyperSensitivity

A physical condition in which a person can feel Electromagnetic radiation, or when he experiences health and physical symptoms when exposed to different kinds of EMR. About 10% of the population is EHS (only 3% are aware of that). The basic symptoms of EHS are headaches, chronic fatigue, joint pain, memory problems, and more.

EMF/EMR(Electromagnetic Fields/Electromagnetic Radiation)

EMR or EMF is a general name of all types of Electromagnetic radiation.

MW or RF - "Microwave radiation" or "Radio Frequencies"

A general name for High frequency electromagnetic radiation between 0.1 to 300 GHz. This radiation is emitted from all electronic wireless communication devices that are based on radio signals for example: Radar, TV and radio broadcast, WIFI, wireless phones, mobile phones, Bluetooth, satellite communication, wireless communication systems, wireless point to point systems and more. 

Radio frequency  - http://en.wikipedia.org/wiki/Radio_frequency

Microwave radiation - http://en.wikipedia.org/wiki/Microwave_radiation

Frequencies of MW or RF

  • 100KHz-300GHz

Units of MW or RF

  • uW/cm2
  • mW/m2
  • 10mV/m2=1uW/cm2
  • V/m - eectric field units.

Spesific types and sources of MW or RF

  • Radar
  • TV and radio broadcast
  • WIFI
  • Wireless phones
  • Mobile phones
  • Bluetooth
  • Satellite communication
  • Wireless communication systems
  • Wireless point to point systems
RF sources list, details and pictures

Characteristics of MW or RF

  • Very directional
  • Relatively easy to stop and block (compared to ELF easier and cheaper to block).

Other names of MW or RF

  • Radio frequencies (RF)
  • Microwave radiation (WM) 
  • High frequency EMR
  • Wireless radiation
  • High frequency field
  • Cellular radiation

Cellular radiation 

Cellular radiation is a RF radiation that is emitted from cellular devices (phones) and base stations (masts).

ELF - Extreme Low Frequencies

Electromagnetic radiation in extremely low frequency, around the 50 Hz which is emitted from electronic and electric devices, power lines, motors, electric and electronic transdormers, electric appliances and more. Its  intensity usualy decreases significantly after few meters, but it is very expensive and difficult to block it.

Frequencies of ELF 

  • 0Hz-300Hz
  • Mostly 50 or 60Hz

Units of ELF

  • mG - miliGauss
  • uT - micro Tesla

Spesific types and sources of ELF

  • Every electric cable
  • Electric appliances
  • Electric power plants and infrastructure
ELF sources list, details and pictures

Characteristics of ELF

  • Not directional
  • Very hard to stop and block (compared to RF)

Other names of ELF

  • Electric radiation
  • Magnetic radiation
  • Electromagnetic radiation
  • Electric Field
  • Magnetic Field

Dirty Electricity 

High frequency noise that is created by electronic and none linear electric components. The noise is then being "moved" over the electric wires all around the house. Dirty Electricity is emitted from the electric wires and "covers" all the house. People that are exposed to high levels of Dirty Electricity react in different ways some experience EHS related symptoms, or neurological symptoms. 



Frequency is the number of times that a certain cycle phenomena accord in a single second. If for example I am clapping my hands, and I manage to do it 10 times in a single second (just imagine I could) then the frequency of my action would be 10 Hz. If I manage to do it 10000 times, then the frequency would be 10000Hz or 10KHz for short.
The number of cycles in a second of an electric signal is the signal's frequency.

1,000 = K = Kilo
1,000,000 = M = Mega
1,000,000,000 = G = Giga

Electric Field

One part of electromagnetic radiation. An electric field is created when there is a difference in electric potential between 2 points. 

Magnetic Field

The second part of electromagnetic radiation. An Magnetic field is created around an electric wire when an electric current is running via it.
