8. What has the FDA done to
measure the Radio Frequency
energy coming from wireless
phones?
The Institute of Electricaand
Electronic Engineers (IEEE) is
developing a technicastandard 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:
ExperimentaTechniques", 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 modeof 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 smalpart 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 Radio
Frequency 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 potentiarisks, you can take a
few simple steps to minimize your
exposure to Radio Frequency (RF)
energy. Since time is a key factor
in how much exposure a person
receives, reducing the amount of
time spent using a wireless phone
wilreduce 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 levedrops
off dramatically with distance. For
