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 con-
sistency 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.
