Health and safety information126Consumer Information on Wireless PhonesThe U.S. Food and Drug Administration (FDA) haspublished a series of Questions and Answers forconsumers relating to radio frequency (RF) exposurefrom wireless phones. The FDA publication includesthe following information:What kinds of phones are the subject of thisupdate?The term wireless phone refers here to hand-heldwireless phones with built-in antennas, often called“cell,” “mobile,” or “PCS” phones. These types ofwireless phones can expose the user to measurableradio frequency energy (RF) because of the shortdistance between the phone and the user's head.These RF exposures are limited by FederalCommunications Commission safety guidelines thatwere developed with the advice of FDA and otherfederal health and safety agencies. When the phone islocated at greater distances from the user, theexposure to RF is drastically lower because a person'sRF exposure decreases rapidly with increasingdistance from the source. The so-called “cordlessphones,” which have a base unit connected to thetelephone wiring in a house, typically operate at farlower power levels, and thus produce RF exposureswell within the FCC's compliance limits.Do wireless phones pose a health hazard?The available scientific evidence does not show thatany health problems are associated with usingwireless phones. There is no proof, however, thatwireless phones are absolutely safe. Wireless phonesemit low levels of radio frequency energy (RF) in themicrowave range while being used. They also emitvery low levels of RF when in the stand-by mode.Whereas high levels of RF can produce health effects(by heating tissue), exposure to low level RF that doesnot produce heating effects causes no known adversehealth effects. Many studies of low level RF exposureshave not found any biological effects. Some studieshave suggested that some biological effects mayoccur, but such findings have not been confirmed byadditional research. In some cases, other researchershave had difficulty in reproducing those studies, or indetermining the reasons for inconsistent results.
