must report the RF exposure level
for each model of phone to the FCC.
The FCC website
(http://www.fcc.gov/cgb/cellular.html)
gives directions for locating the FCC
identification number on your phone
so you can find your phone’s RF
exposure level in the online listing.
8. What has the FDA done to
measure the Radio Frequency energy
coming from wireless phones?
The Institute of Electrical and
Electronic Engineers (IEEE) is
developing a technical standard for
measuring the Radio Frequency (RF)
energy exposure from wireless
phones and other wireless handsets
with the participation and leadership
of FDA 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
