62Consumer Informationon Wireless PhonesThe U.S. Food and DrugAdministration (FDA) haspublished a series of Questionsand Answers for consumersrelating to radio frequency (RF)exposure from wireless phones.The FDA publication includesthe following information:What kinds of phones arethe subject of this update?The term wireless phone refershere to hand-held wirelessphones with built-in antennas,often called “cell,” “mobile,” or“PCS” phones. These types ofwireless phones can expose theuser to measurable radiofrequency energy (RF) becauseof the short distance betweenthe phone and the user's head.These RF exposures are limitedby Federal CommunicationsCommission safety guidelinesthat were developed with theadvice of FDA and other federalhealth and safety agencies.When the phone is located atgreater distances from the user,the exposure to RF is drasticallylower because a person's RFexposure decreases rapidly withincreasing distance from thesource. The so-called “cordlessphones,” which have a base unitconnected to the telephonewiring in a house, typicallyoperate at far lower powerlevels, and thus produce RFexposures well within the FCC'scompliance limits.Do wireless phones pose ahealth hazard?The available scientific evidencedoes not show that any healthproblems are associated withusing wireless phones. There isno proof, however, that wirelessphones are absolutely safe.Wireless phones emit low levelsof radio frequency energy (RF)in the microwave range whilebeing used. They also emit verylow levels of RF when in thestand-by mode. Whereas highlevels of RF can produce healtheffects (by heating tissue),exposure to low level RF thatdoes not produce heatingeffects causes no knownadverse health effects. Manystudies of low level RFexposures have not found anybiological effects. Some studieshave suggested that somebiological effects may occur, butsuch findings have not beenconfirmed by additionalresearch. In some cases, otherresearchers have had difficultyin reproducing those studies, orin determining the reasons forinconsistent results.
