Exposure to very high RF intensities can result in heating of biological tissue and an increase in body temperature . Tissue damage in humans could occur during exposure to high RF levels because of the body’s inability to cope with or dissipate the excessive heat that could be generated.
Read moreWhat uses RF frequency?
Modern devices often generate electromagnetic fields of radio frequency (RF) ranging from 100 kHz to 300 GHz. Key sources of RF fields include mobile phones, cordless phones, local wireless networks and radio transmission towers . They are also used by medical scanners, radar systems and microwave ovens.
