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.
10. 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 use and increasing the
