== European regulations ==

Specific energy absorption rate (SAR) averaged over the whole body or over parts of the body, is defined as the rate at which energy is absorbed per unit mass of body tissue and is expressed in watts per kilogram (W/kg).

Whole body SAR is a widely accepted measure for relating adverse thermal effects to RF exposure.<ref>{{CELEX|31999H0519|text=1999/519/EC: Council Recommendation of 12 July 1999 on the limitation of exposure of the general public to electromagnetic fields (0 Hz to 300 GHz).}}</ref>
