during day-to-day use of wireless devices. Many factors affect this measurement,such as the angle at which the device is held, or which model of device is used.What is FDA doing to find out more about the possible health effects ofwireless device RF?FDA is working with the U.S. National Toxicology Program and with groups ofinvestigators around the world to ensure that high priority animal studies areconducted to address important questions about the effects of exposure to radiofrequency energy (RF).FDA has been a leading participant in the World Health Organization internationalElectromagnetic Fields (EMF) Project since its inception in 1996. An influential resultof this work has been the development of a detailed agenda of research needs thathas driven the establishment of new research programs around the world. TheProject has also helped develop a series of public information documents on EMFissues.FDA and Cellular Telecommunications & Internet Association (CTIA) have a formalCooperative Research and Development Agreement (CRADA) to do research onwireless device safety. FDA provides the scientific oversight, obtaining input fromexperts in government, industry, and academic organizations. CTIA-funded researchis conducted through contracts to independent investigators. The initial research willinclude both laboratory studies and studies of wireless device users. The CRADA willalso include a broad assessment of additional research needs in the context of thelatest research developments around the world.What steps can I take to reduce my exposure to radio frequency energy frommy wireless device?If there is a risk from these products - and at this point we do not know that there is -it is probably very small. But if you are concerned about avoiding even potential risks,you can take a few simple steps to minimize your exposure to radio frequencyenergy (RF). Since time is a key factor in how much exposure a person receives,reducing the amount of time spent using a wireless device will reduce RF exposure. “If you must conduct extended conversations by wireless device every day,you could place more distance between your body and the source of the RF,since the exposure level drops off dramatically with distance. For example,you could use a headset and carry the wireless device away from your body.Again, the scientific data do not demonstrate that wireless devices are harmful. But ifyou are concerned about the RF exposure from these products, you can usemeasures like those described above to reduce your RF exposure from wirelessdevice use.What about children using wireless devices?The scientific evidence does not show a danger to users of wireless devices,including children and teenagers. If you want to take steps to lower exposure to radiofrequency energy (RF), the measures described above would apply to children andteenagers using wireless devices. Reducing the time of wireless device use andincreasing the distance between the user and the RF source will reduce RFexposure.Some groups sponsored by other national governments have advised that childrenbe discouraged from using wireless devices at all. For example, the government inthe United Kingdom distributed leaflets containing such a recommendation in
