Safety 7. How can I find out how much Radio Frequency energy exposure I can get by using my wireless 8. What has the FDA done to measure the Radio Frequency energy coming from wireless phones? phone? The Institute of Electrical and Electronic Engineers All phones sold in the United States must comply with (IEEE) is developing a technical standard for Federal Communications Commission (FCC) measuring the Radio Frequency (RF) energy exposure guidelines that limit Radio Frequency (RF) energy from wireless phones and other wireless handsets exposures. The FCC established these guidelines in with the participation and leadership of FDA consultation with the FDA and the other federal scientists and engineers. The standard, health and safety agencies. The FCC limit for RF "Recommended Practice for Determining the Spatial- exposure from wireless phones is set at a Specific Peak Specific Absorption Rate (SAR) in the Human Absorption Rate (SAR) of 1.6 watts per kilogram (1.6 Body Due to Wireless Communications Devices: W/kg). The FCC limit is consistent with the safety Experimental Techniques", sets forth the first standards developed by the Institute of Electrical and consistent test methodology for measuring the rate Electronic Engineering (IEEE) and the National at which RF is deposited in the heads of wireless Council on Radiation Protection and Measurement. phone users. The test method uses a tissue- Safety The exposure limit takes into consideration the body's ability to remove heat from the tissues that absorb energy from the wireless phone and is set well below levels known to have effects. Manufacturers of wireless phones must report the RF exposure level for each model of phone to the FCC. The FCC website (http://www.fcc.gov/oet/rfsafety) gives directions for locating the FCC identification number on your phone so you can find your phone's RF exposure level in the online listing. simulating model of the human head. Standardized SAR test methodology is expected to greatly improve the consistency of measurements made at different laboratories on the same phone. SAR is the measurement of the amount of energy absorbed in tissue, either by the whole body or a small part of the body. It is measured in watts/kg (or milliwatts/g) of matter. This measurement is used to determine whether a wireless phone complies with safety guidelines. 92
