10. What about children using wireless phones?

Thescientificevidencedoesnotshowadangertousersofwirelessphones,including

childrenandteenagers.Ifyouwanttotakestepstolowerexposuretoradiofrequency

energy(RF),themeasuresdescribedabovewouldapplytochildrenandteenagers

usingwirelessphones.Reducingthetimeofwirelessphoneuseandincreasingthe

distancebetweentheuserandtheRFsourcewillreduceRFexposure.Somegroups

sponsoredbyothernationalgovernmentshaveadvisedthatchildrenbediscouraged

fromusingwirelessphonesatall.Forexample,thegovernmentintheUnitedKingdom

distributedleafletscontainingsucharecommendationinDecember2000.Theynoted

thatnoevidenceexiststhatusingawirelessphonecausesbraintumorsorotherill

effects.Theirrecommendationtolimitwirelessphoneusebychildrenwasstrictly

11. What about wireless phone interference with medical equipment?

Radiofrequencyenergy(RF)fromwirelessphonescaninteractwithsomeelectronic

devices.Forthisreason,theFDAhelpeddevelopadetailedtestmethodtomeasure

electromagneticinterference(EMI)ofimplantedcardiacpacemakersanddefibrillators

fromwirelesstelephones.Thistestmethodisnowpartofastandardsponsoredbythe

AssociationfortheAdvancementofMedicalinstrumentation(AAMI).Thefinaldraft,a

jointeffortbytheFDA,medicaldevicemanufacturers,andmanyothergroups,was

completedinlate2000.Thisstandardwillallowmanufacturerstoensurethatcardiac

pacemakersanddefibrillatorsaresafefromwirelessphoneEMI.TheFDAhastested
