Appendix B
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.
11. What about wireless phone interference with medical equipment?
Radiofrequency energy (RF) from wireless phones can interact with some electronic
devices. For this reason, FDA helped develop a detailed test method to measure
electromagnetic interference (EMI) of implanted cardiac pacemakers and defibrillators
from wireless telephones. This test method is now part of a standard sponsored by
the Association for the Advancement of Medical instrumentation (AAMI). The
final draft, a joint effort by FDA, medical device manufacturers, and many other
groups, was completed in late 2000. This standard will allow manufacturers to
ensure that cardiac pacemakers and defibrillators are safe from wireless phone EMI.
