Since 1996, the Federal Communications Commission (FCC) has required that all wireless communications devices sold in the United States meet its minimum guidelines for safe human exposure to radiofrequency energy. These guidelines specify exposure limits for hand-held wireless devices in terms of the Specific Absorption Rate (SAR). The SAR is a measure of the rate that RF energy is absorbed by the human body. For exposure to RF energy from wireless devices, the allowable SAR limit is 1.6 watts per kilogram (W/kg), as averaged over one gram of tissue. For example, all wireless devices sold in the U.S. go through a formal FCC approval process
