energy. 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 on a daily basis,

consider placing 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 does 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.

11. What about wireless phone interference with

medical equipment?

Radio Frequency (RF) energy from wireless phones

can interact with some electronic devices. For this

reason, the FDA helped develop a detailed test

method to measure Electro Magnetic 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 the 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
