What has FDA done to measure the
radiofrequency energy coming from
wireless phones?
The Institute of Electrical and Electronic Engineers (IEEE) is
developing a technical standard for measuring the radiofrequency
energy (RF) 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 wireless phone complies with
safety guidelines.
What steps can I take to reduce my
exposure to radiofrequency energy from my
wireless phone?
If there is a risk from these products--and at this point we do not
know that there is--it is probably very small. But if you are
concerned about avoiding even potential risks, you can take a few
simple steps to minimize your exposure to radiofrequency energy
(RF). Since time is a key factor in how much exposure a person
