TheNationalInstitutesofHealthparticipatesinsomeinteragencyworkinggroup
activities,aswell.
TheFDAsharesregulatoryresponsibilitiesfortabletswiththeFederalCommunications
Commission(FCC).AlltabletsthataresoldintheUnitedStatesmustcomplywithFCC
safetyguidelinesthatlimitRFexposure.TheFCCreliesontheFDAandotherhealth
agenciesforsafetyquestionsabouttablets.
TheFCCalsoregulatesthebasestationsthatthetabletnetworksrelyupon.While
thesebasestationsoperateathigherpowerthandothetabletsthemselves,theRF
exposuresthatpeoplegetfromthesebasestationsaretypicallythousandsoftimes
lowerthanthosetheycangetfromtablets.Basestationsarethusnotthesubjectofthe

3. What kinds of devices are the subject of this
update?
Theterm“wirelessdevice”refersheretohandheldwirelessdeviceswithbuilt-in
antennas,oftencalled“cell”,“mobile”,or“PCSdevices.Thesetypesofwireless
devicescanexposetheusertomeasurableRadioFrequency(RF)energybecauseof
theshortdistancebetweenthedeviceandtheuser’shead.
TheseRFexposuresarelimitedbyFCCsafetyguidelinesthatweredevelopedwith
theadviceoftheFDAandotherfederalhealthandsafetyagencies.Whenthedevice
islocatedatgreaterdistancesfromtheuser,theexposuretoRFisdrasticallylower
becauseapersonsRFexposuredecreasesrapidlywithincreasingdistancefromthe
source.
