Appendix B
Manufacturers of wireless phones must report the RF exposure level for each
model of phone to the FCC. The FCC website (http://www.fcc.gov/oet/rfsafety)
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 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 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 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 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.
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 and teenagers
using wireless phones. Reducing the time of wireless phone use and increasing
the distance between the user and the RF source will reduce RF exposure.Some
groups sponsored by other national governments have advised that children be
discouraged from using wireless phones at all. For example, the government in the
United Kingdom distributed leaflets containing such a recommendation in
December 2000. They noted that no evidence exists that using a wireless phone
causes brain tumors or other ill effects. Their recommendation to limit wireless
phone use by children was strictly precautionary; it was not based on scientific
evidence that any health hazard exists.
