The threshold level is a SAR value for the whole body of 4 watts per kilogram (4 W/kg).
The most restrictive limits on whole-body exposure are in the frequency range of 30-300 MHz where the RF energy is absorbed most efficiently when the whole body is exposed.
Is RF radiation harmful?
It has been known for many years that exposure to very high levels of RF radiation can be harmful due to the ability of RF energy to heat biological tissue rapidly. Exposure to very high RF intensities can result in heating of biological tissue and an increase in body temperature.
What is acceptable level of EMF?
No known health effects are expected if your exposure to EMF falls below the levels in the following guidelines: natural electromagnetic fields (like those created by the sun): 200 V/m. power mains (not close to power lines): 100 V/m. power mains (close to power lines): 10,000 V/m. microwave ovens: 14 V/m.
What frequencies are harmful to humans?
Low frequency sounds can be harmful
Human beings are normally able to detect sounds in the range of 20-20,000 Hz and it is well known that sounds within this range can damage the hearing. However, sounds under the frequency of 20 Hz can also affect the ear even though we are unable to hear them.
What are symptoms to overexposure of RF radiation?
Describes the health effects on six men exposed to high levels of RF radiation (100 MHz) while working on transmission masts. Symptoms included headache, paresthesia, diarrhea, malaise and lassitude.
