    Typical RF energy levels encountered by the general public are well below the level needed to cause significant heating, but certain workplace environments near high power RF sources may exceed safe exposure limits. [7] A measure of the heating effect is the specific absorption rate or SAR, which has units of watts per kilogram (W/kg).
