scientists and engineers. The standard, "Recommended Practice for Determining
the Spatial-Peak 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 measures described above would apply to children and teenagers using
