Health and Safety Information 135What 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 that highpriority animal studies are conducted to address importantquestions about the effects of exposure to radio frequencyenergy (RF).FDA has been a leading participant in the World HealthOrganization international Electromagnetic Fields (EMF) Projectsince its inception in 1996. An influential result of this work hasbeen the development of a detailed agenda of research needsthat has driven the establishment of new research programsaround the world. The Project has also helped develop a series ofpublic information documents on EMF issues.FDA and Cellular Telecommunications & Internet Association(CTIA) have a formal Cooperative Research and DevelopmentAgreement (CRADA) to do research on wireless phone safety.FDA provides the scientific oversight, obtaining input fromexperts in government, industry, and academic organizations.CTIA-funded research is conducted through contracts toindependent investigators. The initial research will include bothlaboratory studies and studies of wireless phone users. TheCRADA will also include a broad assessment of additionalresearch needs in the context of the latest researchdevelopments around the world.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 do notknow that there is - it is probably very small. But if you areconcerned about avoiding even potential risks, you can take afew simple steps to minimize your exposure to radio frequencyenergy (RF). Since time is a key factor in how much exposure aperson receives, reducing the amount of time spent using awireless phone will reduce RF exposure.• If you must conduct extended conversations by wireless phone everyday, you could place more distance between your body and the sourceof the RF, since the exposure level drops off dramatically with distance.For example, you could use a headset and carry the wireless phoneaway from your body or use a wireless phone connected to a remoteantenna.Again, 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 like thosedescribed above to reduce your RF exposure from wireless phoneuse.
