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 moreWhat is extremely low frequency EMF?
Extremely low frequency (ELF) electric and magnetic fields (EMF) occupy the lower part of the electromagnetic spectrum in the frequency range 0-3000 Hz . ELF EMF result from electrically charged particles.

Read moreWhat are low mid and high frequencies?
Mid frequency is comprised of the sounds we perceive most often on a day to day basis and fall into the range of 200-2,000 Hz. Anything below 200 Hz is considered low frequency and anything above 2,000 Hz is high frequency sound .
Read moreWhat is the frequency range of radio frequency?
Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz) .
Read moreWhat is high frequency and low frequency?
The lower the frequency, the fewer the oscillations. High frequencies produce more oscillations . The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz.
Read moreWhy do we use high or low frequency scheme?
This type of radiation can also travel further distances around the Earth than other types of radiation, for reasons we will discuss later. Therefore HF and lower frequency radiation is the best to use for direct long distance communications (when satellites or long cables cannot be used).22 Eki 2003
