Electromagnetic fields - World Health Organization (WHO)
Electric and magnetic fields are part of the spectrum of electromagnetic radiation which extends from static electric and magnetic fields, through radiofrequency and infrared radiation, to X-rays.
Health effects of Radiofrequency Electromagnetic Fields (RF EMF)
People are exposed to man-made EMF both in their occupational environments and in everyday life. Most common technology-related EMF include radiofrequency (RF) EMF, i.e. radiowaves and microwaves (100 kHz–300 GHz), and power frequency EMF (50, 60 Hz).
Electromagnetic Field Radiation - Environment, Health and Safety
EMF includes both electrical and magnetic fields emanating from electrical devices. The electromagnetic radiation is in the frequency range of 50/60 Hz (from typical power lines) through the RF range (wireless networks at 2.4 – 5.8 GHz) up to 300 GHz (microwave devices).
The International EMF Project - World Health Organization …
Concerns have been expressed that exposure to extremely low frequency (ELF) magnetic fields at power frequencies (50/60 Hz) could lead to an increased incidence of cancer in children and other adverse health effects. The evidence comes …
