8. What has FDA done to measure the radiofrequency
energy coming from wireless phones ?
The Institute of Electrical and Electronic Engineers (IEEE)
is developing a technical standard for measuring the
radiofrequency energy (RF) exposure from wireless
phones and other wireless handsets with the
participation and leadership of FDA scientists anring 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
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 condict extended
conversationsby 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 distamce. 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.
