X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10−8 to 10−12 metre and corresponding frequencies from about 10 16 to 10 20 hertz (Hz).

Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
Read moreWhat low frequency is harmful to humans?
In the past 30 years the concern that daily exposure to extremely low-frequency magnetic fields (ELF-EMF) (1 to 300 Hz ) might be harmful to human health (cancer, neurobehavioral disturbances, etc) has been the object of debate, and has become a public health concern.
Read moreWhat is the effect of extremely low frequency?
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 is extremely low frequency used for?
Extremely low frequency (ELF) electromagnetic waves are currently the lowest frequency waves used routinely for wireless communication .15 Nis 2003
Read moreWhat is low frequency and high frequency?
Low-frequency sounds are 500 Hz or lower while high-frequency waves are above 2000 Hz . Human ears can register sounds from about 20 Hz in frequency up to 20,000 Hz, depending of course, upon the hearer. People with hearing loss usually have trouble hearing sounds in the higher frequency range.6 Eki 2017
