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.
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 scientific data do not demonstrate that
wireless phones are harmful. But if you are concerned
about the RF exposure from these products, you can
use measures like those described above to reduce your
RF exposure from wireless phone use.
What about children using wireless
phones?
The scientific evidence does not show a danger to users
of wireless phones, including children and teenagers. If
you want to take steps to lower exposure to
radiofrequency energy (RF), the measures described
above would apply to children and teenagers using
wireless phones. Reducing the time of wireless phone
