The issue of extremely low frequency (ELF) biological effects is very controversial. Research has focused on possible carcinogenic, reproductive, and neurological effects . Other suggested health effects include cardiovascular, brain and behavior, hormonal and immune system changes.
Read moreHow do you prevent low-frequency magnetic fields?
The most common solution for shielding low frequency EMI is to use a high permeability magnetic shielding sheet metal or foil . Typical examples of shielding foils include specialty ferromagnetic alloys branded as MuMetal®, Netic®, Finemet® and Metglas® to name a few.
Read moreWhat is considered extremely low frequency?
Extremely low frequency (ELF) is the ITU designation for electromagnetic radiation (radio waves) with frequencies from 3 to 30 Hz , and corresponding wavelengths of 100,000 to 10,000 kilometers, respectively. In atmospheric science, an alternative definition is usually given, from 3 Hz to 3 kHz.
Read moreIs low or high frequency dangerous?
So the power delivered by a low frequency radiation comes in a great number of small packets, while the same amount of power carried by an higher frequency radiations is composed by few large packets. This is the reason why high frequency radiation is more harmful than lower frequency radiation .
Read moreAre low frequencies harmful?
Some recent epidemiologic studies have suggested that the exposure to extremely low frequency (ELF) electromagnetic fields (EMF) affect human health , because of the incidence of certain types of cancer, depression, and miscarriage have been increased among individuals living or working in environments exposed to such …
