Safety Guidelines
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?
Radio frequency energy (RF) from wireless phones can
interact with some electronic devices. For this reason,
the 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 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
