Safety Guidelines
TheFDAbelongstoaninteragencyworkinggroupofthefederalagenciesthathave
responsibilityfordifferentaspectsofRFsafetytoensurecoordinatedeffortsatthe
federallevel.Thefollowingagenciesbelongtothisworkinggroup:
•
NationalInstituteforOccupationalSafetyandHealth
•
EnvironmentalProtectionAgency
•
OccupationalSafetyandHealthAdministration(Administracióndelaseguridady
saludlaborales)
•
OccupationalSafetyandHealthAdministration
•
NationalTelecommunicationsandInformationAdministration
TheNationalInstitutesofHealthparticipatesinsomeinteragencyworkinggroup
activities,aswell.
TheFDAsharesregulatoryresponsibilitiesforwirelessphoneswiththeFederal
CommunicationsCommission(FCC).Allphones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wirelessphones.
TheFCCalsoregulatesthebasestationsthatthewirelessphonenetworksrelyupon.
Whilethesebasestationsoperateathigherpowerthandothewirelessphones
themselves,theRFexposuresthatpeoplegetfromthesebasestationsaretypically
thousandsoftimeslowerthanthosetheycangetfromwirelessphones.Basestations
arethusnotthesubjectofthesafetyquestionsdiscussedinthisdocument.
3. What kinds of phones are the subject of this update?
Theterm
‘wirelessphone’
refersheretohandheldwirelessphoneswithbuiltin
antennas,oftencalled‘cell’,‘mobile’,or‘PCS’phones.Thesetypesofwirelessphones
canexposetheusertomeasurableradiofrequencyenergy(RF)becauseoftheshort
distancebetweenthephone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phoneislocatedatgreaterdistancesfromthe
user,theexposuretoRFisdrasticallylowerbecauseaperson’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farbelowtheFCCsafetylimits.
