Specific Absorption Rate (SAR)
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
tissue-simulating 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 Radio
Frequency 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 Radio Frequency (RF)
energy. 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
Radio Frequency (RF) energy, the
