Appendix B Message from the FDA
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.
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
