1300102030405060708131Health Organization International Electromagnetic Fields (EMF) Project since itsinception in 1996. An influential result of this work has been the developmentof a detailed agenda of research needs that has driven the establishment of newresearch programs around the world.The Project has also helped develop a series of public information documentson EMF issues. FDA and the Cellular Telecommunications & Internet Association(CTIA) have a formal Cooperative Research and Development Agreement(CRADA) to do research on wireless phone safety. FDA provides the scientificoversight, obtaining input from experts in government, industry, and academicorganizations. CTIA-funded research is conducted through contracts toindependent investigators. The initial research will include both laboratorystudies and studies of wireless phone users. The CRADA will also include a broadassessment of additional research needs in the context of the latest researchdevelopments around the world.7. How can I find out how much radiofrequency energy exposure I can getby using my wireless phone?All phones sold in the United States must comply with Federal CommunicationsCommission (FCC) guidelines that limit radiofrequency energy (RF) exposures.FCC established these guidelines in consultation with FDA and the otherfederal health and safety agencies. The FCC limit for RF exposure from wirelesstelephones is set at a Specific Absorption Rate (SAR) of 1.6 watts per kilogram(1.6 W/kg). The FCC limit is consistent with the safety standards developed bythe Institute of Electrical and Electronic Engineering (IEEE) and the NationalCouncil on Radiation Protection and Measurement. The exposure limit takesinto consideration the body’s ability to remove heat from the tissues that absorbenergy from the wireless phone and is set well below levels known to haveeffects. Manufacturers of wireless phones must report the RF exposure levelfor each model of phone to the FCC. The FCC website (http://www.fda.gov(under “c” in the subject index, select Cell Phones > Research)) gives directionsfor locating the FCC identification number on your phone so you can find yourphone’s RF exposure level in the online listing.8. What has FDA done to measure the radiofrequency energy coming fromwireless phones ?The Institute of Electrical and Electronic Engineers (IEEE) is developing a technicalstandard for measuring the radiofrequency energy (RF) exposure from wirelessphones and other wireless handsets with the participation and leadership of FDAscientists and engineers. The standard, “Recommended Practice for Determiningthe Spatial-Peak Specific Absorption Rate (SAR) in the Human Body Due toWireless Communications Devices: Experimental Techniques,” sets forth the firstconsistent test methodology for measuring the rate at which RF is depositedin the heads of wireless phone users. The test method uses a tissue-simulatingmodel of the human head. Standardized SAR test methodology is expected togreatly improve the consistency of measurements made at different laboratorieson the same phone. SAR is the measurement of the amount of energy absorbedin tissue, either by the whole body or a small part of the body. It is measured inwatts/kg (or milliwatts/g) of matter. This measurement is used to determinewhether a wireless phone complies with safety guidelines.9. What steps can I take to reduce my exposure to radiofrequency energyfrom my wireless phone?If there is a risk from these products—and at this point we do not know thatthere is—it is probably very small. But if you are concerned about avoiding evenpotential risks, you can take a few simple steps to minimize your exposure toradiofrequency energy (RF). Since time is a key factor in how much exposure aperson receives, reducing the amount of time spent using a wireless phone willreduce RF exposure.
