SAR
Specific Absorption Rate (SAR) measures how much radiofrequency energy from devices like cell phones is absorbed by the body. It is expressed in watts per kilogram (W/kg). SAR helps assess the safety of wireless devices by estimating the potential heating effects on tissues. Regulatory agencies set limits to ensure devices operate within safe levels, minimizing any health risks. In simple terms, SAR indicates how much energy your body might absorb when using a device that emits electromagnetic waves, ensuring the exposure remains within established safety standards.
