Health and safety information36Consumer Information on WirelessPhonesThe U.S. Food and Drug Administration(FDA) has published a series of Questionsand Answers for consumers relating to radiofrequency (RF) exposure from wirelessphones. The FDA publication includes thefollowing information:What kinds of phones are the subjectof this update?The term wireless phone refers here tohand-held wireless phones with built-inantennas, often called “cell,” “mobile,” or“PCS” phones. These types of wirelessphones can expose the user to measurableradio frequency energy (RF) because of theshort distance between the phone and theuser's head. These RF exposures are limitedby Federal Communications Commissionsafety guidelines that were developed withthe advice of FDA and other federal healthand safety agencies. When the phone islocated at greater distances from the user,the exposure to RF is drastically lowerbecause a person's RF exposure decreasesrapidly with increasing distance from thesource. The so-called “cordless phones,”which have a base unit connected to thetelephone wiring in a house, typicallyoperate at far lower power levels, and thusproduce RF exposures well within the FCC'scompliance limits.Do wireless phones pose a healthhazard?The available scientific evidence does notshow that any health problems areassociated with using wireless phones. Thereis no proof, however, that wireless phonesare absolutely safe. Wireless phones emitlow levels of radio frequency energy (RF) inthe microwave range while being used. They
