About Electromagnetic Radiation (EMR)

What is Electromagnetic radiation (EM radiation or EMR)?

Energy travels throughout the universe at the speed of light in the form of electromagnetic radiation, which may be imparted energy to matter it interacts with.
The EM Spectrum starts from radio waves (long wavelength, smaller frequency) to gamma rays (very short wave length, bigger frequency).

How is EM radiation produced?

-It is produced when electricity flows through a conductor thereby inducing a magnetic field.
-Both the electric and magnetic field make up the Electro-magnetic field and this field radiates out from the source.

What is Electro-smog?

Electrosmog is the invisible electromagnetic radiation resulting from the use of both wireless technology and mains electricity. It is considered as the 4th type of pollution. The common sources of electrosmog are Cordless phones, Cordless baby alarms, Mobile/cellular phone masts / towers, cell phones, WiFi, High Tension Cables, Radar / Server or Control Rooms, Areas of high density of Electrical / Electronic equipment.

Frequency range of the EM Radiation Spectrum
Extremely Low Frequency (ELF) – Frequencies up to 300 Hz (i.e. 50/60Hz electrical appliances)
Radiofrequency(RF)300Hz – 300MHz
Microwaves(MW)300MHz – 300GHz

Decibel (dB) –

Decibel , dB is commonly used for expressing sound intensity however, is not a unit of measurement but the ratio of one intensity measurement to another. It is used to compare the field intensity before and after an event, or compare a measured intensity to a known reference.We also use it to express the effectiveness of a shield. This table shows that a Shielding effectiveness of 20 dB, can attenuate up to 99% of the RF/ microwave radiation.

Need For Shielding

The need for shielding comes from the mounting evidence that seem to show detrimental health effects from over exposure to electro-smog/EM radiation. Below is a summary from the The Federal Office for the Environment FOEN, Switzerland that explains the concern about electro-smog.

Low-frequency magnetic fields and cancer Assessment of scientific studies in the low dose range.

In 2002, the International Agency for Research on Cancer (IARC) assessed low frequency magnetic fields such as those that result from the production and use of electricity as “possibly carcinogenic to humans” (group 2B)……This assessment was based on the findings of epidemiological studies, which indicated an approximately doubled risk of leukaemia for children exposed to average magnetic fields greater than 0.3 to 0.4 µT.
