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 Engineers (IEEE). This standard specifies test methods and
