Appendix B Message from the FDA

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 performance requirements for hearing aids and wireless phones so that no

interference occurs when a person uses a compatible phone and a accompanied

hearing aid at the same time. This standard was approved by the IEEE in 2000.
