7. How can I find out how much radiofrequency energy

exposure I can get by using my wireless device?

AlldevicessoldintheUnitedStatesmustcomplywithFederalCommunications

Commission(FCC)guidelinesthatlimitradiofrequencyenergy(RF)exposures.

TheFCC/ISEDCestablishedtheseguidelinesinconsultationwiththeFDAandthe

otherfederalhealthandsafetyagencies.TheFCC/ISEDClimitforRFexposure

fromwirelessdeviceissetataSpecificAbsorptionRate(SAR)of1.6watts

standards developed by the Institute of Electrical and Electronic Engineering

(IEEE)andtheNationalCouncilonRadiationProtectionandMeasurement.The

exposure limit takes into consideration the body’s ability to remove heat from

the tissues that absorb energy from the wireless device and is set well below

levels known to have effects. Manufacturers of wireless devices must report

theRFexposurelevelforeachmodelofdevicetotheFCC/ISEDC.TheFCC

identification number on your device so you can find your device’s RF exposure level

in the online listing.

8. What has the FDA done to measure the radiofrequency

energy coming from wireless devices?

The Institute of Electrical and Electronic Engineers (IEEE) is developing a technical

standard for measuring the radiofrequency energy (RF) exposure from wireless

devices and other wireless handsets with the participation and leadership of FDA

scientists and engineers. The standard, ‘Recommended Practice for Determining

the Spatial- Peak Specific Absorption Rate (SAR) in the Human Body Due to

WirelessCommunicationsDevices:ExperimentalTechniques,’setsforththefirst

consistent test methodology for measuring the rate at which RF is deposited in

the heads of wireless device users. The test method uses a tissue simulating model

of the human head. Standardized SAR test methodology is expected to greatly

improve the consistency of measurements made at different laboratories on the

same device. SAR is the measurement of the amount of energy absorbed in tissue,

either by the whole body or a small part of the body. It is measured in watts/kg (or

milliwatts/g) of matter. This measurement is used to determine whether a wireless

device complies with safety guidelines.
