Health and safety information149agencies for safety questions about wirelessphones.FCC also regulates the base stations that thewireless phone networks rely upon. While thesebase stations operate at higher power than dothe wireless phones themselves, the RFexposures that people get from these basestations are typically thousands of times lowerthan those they can get from wireless phones.Base stations are thus not the primary subjectof the safety questions discussed in thisdocument.4. What is FDA doing to find out more aboutthe possible health effects of wireless phoneRF?FDA is working with the U.S. NationalToxicology Program and with groups ofinvestigators around the world to ensure thathigh priority animal studies are conducted toaddress important questions about the effectsof exposure to radio frequency energy (RF).FDA has been a leading participant in the WorldHealth Organization InternationalElectromagnetic Fields (EMF) Project since itsinception in 1996. An influential result of thiswork has been the development of a detailedagenda of research needs that has driven theestablishment of new research programsaround the world. The Project has also helpeddevelop a series of public informationdocuments on EMF issues.FDA and the Cellular Telecommunications &Internet Association (CTIA) have a formalCooperative Research and DevelopmentAgreement (CRADA) to do research on wirelessphone safety. FDA provides the scientificoversight, obtaining input from experts ingovernment, industry, and academicorganizations. CTIA-funded research is
