Health and safety information24industry to take a number of steps, including thefollowing:• Support needed research into possible biologicaleffects of RF of the type emitted by wirelessphones;• Design wireless phones in a way that minimizesany RF exposure to the user that is not necessaryfor device function; and• Cooperate in providing users of wireless phoneswith the best possible information on possibleeffects of wireless phone use on human health.FDA belongs to an interagency working group of thefederal agencies that have responsibility for differentaspects of RF safety to ensure coordinated efforts atthe federal level. The following agencies belong to thisworking group:• National Institute for Occupational Safety andHealth• Environmental Protection Agency• Federal Communications Commission• Occupational Safety and Health Administration• National Telecommunications and InformationAdministrationThe National Institutes of Health participates in someinteragency working group activities, as well.FDA shares regulatory responsibilities for wirelessphones with the Federal Communications Commission(FCC). All phones that are sold in the United Statesmust comply with FCC safety guidelines that limit RFexposure. FCC relies on FDA and other health agenciesfor safety questions about wireless phones.FCC also regulates the base stations that the wirelessphone networks rely upon. While these base stationsoperate at higher power than do the wireless phonesthemselves, the RF exposures that people get fromthese base stations are typically thousands of timeslower than those they can get from wireless phones.Base stations are thus not the primary subject of thesafety questions discussed in this document.
