While research has not conclusively linked cellphone radiation to health risks, the Federal Communications Commission has set restrictions to the specific absorption rate, or SAR, people can receive from hand-held devices.
For exposure to the general public, the FCC allows a maximum SAR of 1.6 watts/kg. Before a phone gets FCC approval for marketing in the United States, it must meet this threshold.
