for Determining the Spatial- Peak
Specifi c Absorption Rate (SAR) in the
Human Body Due to Wireless
Communications Devices:
Experimental Techniques,' sets forth
the fi rst consistent test methodology
for measuring the rate at which RF is
deposited in the heads of wireless
phone users. The test method uses a
tissuesimulating 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. Again, the
