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
