What is a SAR value?

                  What is a SAR value?

 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.
Every mobile phone model is tested for radio wave emissions. Using an internationally standardized method that meets government and regulatory requirements, a measurement is made to determine how much electromagnetic energy is absorbed by body tissue. This gives the SAR (specific absorption rate) value.
Governmental and regulatory agencies have established SAR limits under which cell phone use has been determined by them to be safe.
