100Consumer Information on Wireless PhonesThe U.S. Food and Drug Administration (FDA) has published a series of Questions and Answers for consumersrelating to radio frequency (RF) exposure from wireless phones. The FDA publication includes the followinginformation:What kinds of phones are the subject of this update?The term wireless phone refers here to hand-held wireless phones with built-in antennas, often called "cell,""mobile," or "PCS" phones. These types of wireless phones can expose the user to measurable radio frequencyenergy (RF) because of the short distance between the phone and the user's head. These RF exposures are limitedby Federal Communications Commission safety guidelines that were developed with the advice of FDA and otherfederal health and safety agencies.When the phone is located at greater distances from the user, the exposure to RF is drastically lower because aperson's RF exposure decreases rapidly with increasing distance from the source. The so-called "cordless phones,"which have a base unit connected to the telephone wiring in a house, typically operate at far lower power levels,and thus produce RF exposures well within the FCC's compliance limits.Do wireless phones pose a health hazard?The available scientific evidence does not show that any health problems are associated with using wirelessphones. There is no proof, however, that wireless phones are absolutely safe. Wireless phones emit low levels ofradio frequency energy (RF) in the microwave range while being used. They also emit very low levels of RF when inthe stand-by mode. Whereas high levels of RF can produce health effects (by heating tissue), exposure to low levelRF that does not produce heating effects causes no known adverse health effects. Many studies of low level RFexposures have not found any biological effects. Some studies have suggested that some biological effects mayoccur, but such findings have not been confirmed by additional research. In some cases, other researchers have haddifficulty in reproducing those studies, or in determining the reasons for inconsistent results.What is FDA's role concerning the safety of wireless phones?Under the law, FDA does not review the safety of radiation-emitting consumer products such as wireless phonesbefore they can be sold, as it does with new drugs or medical devices. However, the agency has authority to takeaction if wireless phones are shown to emit radio frequency energy (RF) at a level that is hazardous to the user. Insuch a case, FDA could require the manufacturers of wireless phones to notify users of the health hazard and torepair, replace or recall the phones so that the hazard no longer exists.t239.book Page 100 Wednesday, March 25, 2009 12:48 PM
