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 does
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
