Health and Safety Information254● Occupational Safety and Health Administration● National Telecommunications and InformationAdministration● The National Institutes of Health participates in someinteragency working group activities, as well.FDA shares regulatory responsibilities for wireless phoneswith the Federal Communications Commission (FCC). Allphones that are sold in the United States must comply withFCC safety guidelines that limit RF exposure. FCC relies onFDA and other health agencies for safety questions aboutwireless phones.FCC also regulates the base stations that the wireless phonenetworks rely upon. While these base stations operate athigher power than do the wireless phones themselves, the RFexposures that people get from these base stations aretypically thousands of times lower than those they can getfrom wireless phones. Base stations are thus not the primarysubject of the safety questions discussed in this document.4. What is FDA doing to find out more about the possiblehealth effects of wireless phone RF?FDA is working with the U.S. National Toxicology Program andwith groups of investigators around the world to ensure thathigh priority animal studies are conducted to addressimportant questions about the effects of exposure to radiofrequency energy (RF).FDA has been a leading participant in the World HealthOrganization International Electromagnetic Fields (EMF)Project since its inception in 1996. An influential result of thiswork has been the development of a detailed agenda ofresearch needs that has driven the establishment of newresearch programs around the world. The Project has alsohelped develop a series of public information documents onEMF issues.Health and Safety Information255FDA and the Cellular Telecommunications & InternetAssociation (CTIA) have a formal Cooperative Research andDevelopment Agreement (CRADA) to do research on wirelessphone safety. FDA provides the scientific oversight, obtaininginput from experts in government, industry, and academicorganizations. CTIA-funded research is conducted throughcontracts to independent investigators. The initial researchwill include both laboratory studies and studies of wirelessphone users. The CRADA will also include a broad assessmentof additional research needs in the context of the latestresearch developments around the world.5. What steps can I take to reduce my exposure to radiofrequency energy from my wireless phone?If there is a risk from these products—and at this point we donot know that there is—it is probably very small. But if youare concerned about avoiding even potential risks, you cantake a few simple steps to minimize your exposure to radiofrequency energy (RF). Since time is a key factor in howmuch exposure a person receives, reducing the amount oftime spent using a wireless phone will reduce RF exposure.If you must conduct extended conversations by wirelessphone every day, you could place more distance betweenyour body and the source of the RF, since the exposure leveldrops off dramatically with distance. For example, you coulduse a headset and carry the wireless phone away from yourbody or use a wireless phone connected to a remote antennaAgain, the scientific data do not demonstrate that wirelessphones are harmful. But if you are concerned about the RFexposure from these products, you can use measures likethose described above to reduce your RF exposure fromwireless phone use.
