CTIA-fundedresearch is conducted through contracts to independentinvestigators. The initial research will include bothlaboratory studies and studies of wireless phone users.The CRADA will also include a broad assessment ofadditional research needs in the context of the latestresearch developments 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) guidelinesthat limit radio frequency energy (RF) exposures. FCCestablished these guidelines in consultation with FDAand other federal health and safety agencies. The FCClimit for exposure from wireless telephones is set at aSpecific Absorption Rate (SAR) of 1.6 watts per kilogram(1.6 W/kg). The FCC limit is consistent with the safetystandards developed by the Institute of Electrical andElectronic Engineering (IEEE) and the National Councilon Radiation Protection and Measurement. The exposurelimit takes into consideration the body’s ability to removeheat from the tissue that absorb energy from the wirelessphone and is set well below levels known to have effects.Manufacturers of wireless phones must report the RFexposure level for each model of phone to the FCC. TheFCC website (http://www.fcc.gov/oet/rfsafety) givesdirections for locating the FCC identification number on
