Do wireless phones pose a health hazard?The available scientific evidence does not show that any healthproblems are associated with using wireless phones. There is no proof,however, that wireless phones are absolutely safe. Wireless phones emitlow levels of radiofrequency energy (RF) in the microwave range whilebeing used. They also emit very low levels of RF when in the stand-bymode. Whereas high levels of RF can produce health effects (by heatingtissue), exposure to low level RF that does not produce heating effectscauses no known adverse health effects. Many studies of low level RFexposures have not found any biological effects. Some studies havesuggested that some biological effects may occur, but such findingshave not been confirmed by additional research. In some cases, otherresearchers have had difficulty in reproducing those studies, or indetermining the reasons for inconsistent results.2. What is FDA’s role concerning the safety of wireless phones?Under the law, FDA does not review the safety of radiation-emittingconsumer products such as wireless phones before they can be sold, as itdoes with new drugs or medical devices. However, the agency hasauthority to take action if wireless phones are shown to emitradiofrequency energy (RF) at a level that is hazardous to the user. Insuch a case, FDA could require the manufacturers of wireless phones to
