8. 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.
9. 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 receives,
reducing the amount of time spent using a wireless phone will
reduce RF exposure.
