Safety Guidelines

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.
