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.

If you must conduct extended conversations by wireless phone every day,
you could place more distance between your body and the source of the
RF, since the exposure level drops off dramatically with distance. For
example, you could use a headset and carry the wireless phone away from
your body or use a wireless phone connected to a remote antenna
