7. How can I find out how much Radio Frequency energy

exposure I can get by using my wireless phone?

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

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 phone and is set well below levels known to have effects. Manufacturers

of wireless phones must report the RF exposure level for each model of phone to

theFCC.TheFCCwebsite(

8. What has the FDA done to measure the Radio Frequency

energy coming from wireless phones?

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

standard for measuring the Radio Frequency (RF) energy exposure from wireless

phones 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 phone 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 phone. 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 wir

eless phone complies with safety guidelines.
