104 Copyright © Nokia 2004Consumer Update on Wireless PhonesU.S. Food and Drug Administration1. Do wireless phones pose a health hazard?The available scientific evidence does not show that any health problems are associated withusing wireless phones. There is no proof, however, that wireless phones are absolutely safe.Wireless phones emit low levels of radiofrequency energy (RF) in the microwave range whilebeing used. They also emit very low levels of RF when in the stand-by mode. Whereas highlevels of RF can produce health effects (by heating tissue), exposure to low level RF that doesnot produce heating effects causes no known adverse health effects. Many studies of lowlevel RF exposures have not found any biological effects. Some studies have suggested thatsome biological effects may occur, but such findings have not been confirmed by additionalresearch. In some cases, other researchers have had difficulty in reproducing those studies,or in determining 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-emitting consumer products suchas wireless phones before they can be sold, as it does with new drugs or medical devices.However, the agency has authority to take action if wireless phones are shown to emitradiofrequency energy (RF) at a level that is hazardous to the user. In such a case, FDA couldrequire 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.Although the existing scientific data do not justify FDA regulatory actions, FDA has urgedthe wireless phone industry to take a number of steps, including the following:• Support needed research into possible biological effects of RF of the type emitted bywireless phones;• Design wireless phones in a way that minimizes any RF exposure to the user that is notnecessary for device function; and• Cooperate in providing users of wireless phones with the best possible information onpossible effects of wireless phone use on human health.FDA belongs to an interagency working group of the federal agencies that haveresponsibility for different aspects of RF safety to ensure coordinated efforts at the federallevel. The following agencies belong to this working group:• National Institute for Occupational Safety and Health• Environmental Protection Agency• Federal Communications Commission• Occupational Safety and Health Administration• National Telecommunications and Information AdministrationThe National Institutes of Health participates in some interagency working group activities,as well.FDA shares regulatory responsibilities for wireless phones with the Federal CommunicationsCommission (FCC). All phones that are sold in the United States must comply with FCCsafety guidelines that limit RF exposure. FCC relies on FDA and other health agencies forsafety questions about wireless phones. FCC also regulates the base stations that the wirelessphone networks rely upon. While these base stations operate at higher power than do thewireless phones themselves, the RF exposures that people get from these base stations aretypically thousands of times lower than those they can get from wireless phones. Basestations are thus not the subject of the safety questions discussed in this document.
