Appendix B

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. FDA has

tested hearing aids for interference from handheld wireless phones and helped

develop a voluntary standard sponsored by the Institute of Electrical and Electronic
