Division A EXPOSURE LIMIT VALUES (ELVs)
United Kingdom
Health effects ELVs for frequencies from 100 kHz to 6 GHz (Table A1) are limits for energy and power absorbed per unit mass of body tissue generated from exposure to electric and magnetic fields.
Sensory effects ELVs for frequencies from 0,3 to 6 GHz (Table A2) are limits on absorbed energy in a small mass of tissue in the head from exposure to electromagnetic fields.
Health effects ELVs for frequencies above 6 GHz (Table A3) are limits for power density of an electromagnetic wave incident on the body surface.
Table A1
Health effects ELVs for exposure to electromagnetic fields from 100 kHz to 6 GHz
| Health effects ELVs | SAR values averaged over any six-minute period |
|---|---|
| ELVs related to whole body heat stress expressed as averaged SAR in the body | 0,4 Wkg–1 |
| ELVs related to localised heat stress in head and trunk expressed as localised SAR in the body | 10 Wkg–1 |
| ELVs related to localised heat stress in the limbs expressed as localised SAR in the limbs | 20 Wkg–1 |
Sensory effects ELVs from 0,3 GHz to 6 GHz
This sensory effects ELVs (Table A2) is related to avoiding auditory effects caused by exposures of the head to pulsed microwave radiation.
