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 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 potential risks, 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 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
