Guide to Safe and Responsible Wireless Phone Use135initial research will include both laboratory studiesand studies of wireless phone users. The CRADA willalso include a broad assessment of additionalresearch needs in the context of the latest researchdevelopments around the world.How can I find out how much radio frequency energyexposure I can get by using my wireless phone?All phones sold in the United States must comply withFederal Communications Commission (FCC)guidelines that limit radio frequency energy (RF)exposures. FCC established these guidelines inconsultation with FDA and other federal health andsafety agencies. The FCC limit for exposure fromwireless telephones is set at a Specific AbsorptionRate (SAR) of 1.6 watts per kilogram (1.6 W/kg). TheFCC limit is consistent with the safety standardsdeveloped by the Institute of Electrical andElectronic Engineering (IEEE) and the NationalCouncil on Radiation Protection and Measurement.The exposure limit takes into consideration the body’sability to remove heat from the tissue that absorbenergy from the wireless phone and is set well belowlevels known to have effects.Manufacturers of wireless phones must report the RFexposure level for each model of phone to the FCC.The FCC has granted an Equipment Authorization forthis model phone with all reported SAR levelsevaluated as in compliance with the FCC RFexposure guidelines.
