WHAT IS SAR AND WHAT IS ALL THE FUSS ABOUT?
SAR (specific absorption rate) is an indication of the amount of radiation that is absorbed into a head whilst using a cellular phone, the higher the SAR rating the more radiation that is absorbed into the head.
SPECIFIC ABSORPTION RATE (SAR)
A SAR value is a measure of the maximum energy absorbed by a unit of mass of exposed tissue of a person using a mobile phone, over a given time or more simply the power absorbed per unit mass. SAR values are usually expressed in units of watts per kilogram (W/kg) in either 1g or 10g of tissue.
In Europe, the European Council Recommendation 519/1999/EC for exposure guidelines has adopted the recommendations made by the International Commission on Non-Ionising Radiation Protection (ICNIRP Guidelines 1998). In the US, the FCC, Federal Communications Commission, sets the radio frequency safety guidelines that all phones must meet before being sold in the US. Current reference standards and limits (status January 2001).
