in the Human Body Due to Wireless
Communications Devices: Experimental
Techniques', 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 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 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.
