Läste någonstans om SAR-värde hos mobiler. Vad menas med det?

Wikipedia:

Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed per unit mass by a human body when exposed to a radio frequency (RF) electromagnetic field. It can also refer to absorption of other forms of energy by tissue, including ultrasound. It is defined as the power absorbed per mass of tissue and has units of watts per kilogram (W/kg).

When measuring the SAR due to a mobile phone the phone is placed against a representation of a human head (a "SAR Phantom") in a talk position. The SAR value is then measured at the location that has the highest absorption rate in the entire head, which in the case of a mobile phone is often as close to the phone's antenna as possible.

En del av radiovågorna från en mobiltelefon tas upp av kroppen och omvandlas till värme.
SAR-värdet (Specific Absorption Rate) talar om hur mycket av radiovågornas energi som kroppen absorberar.
