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 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.
