your phone so you can find your phone's RF exposure level in the online listing. What has 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 energy (RF) exposure from wireless phones and other wireless hand sets 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 tissuesimulating 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 wireless phone complies with safety guidelines. 140 Health and Safety Information

What has 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 energy (RF) exposure from wireless
phones and other wireless hand sets 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 wireless phone complies
with safety guidelines.
