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
Safety Guidelines
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 safe
from wireless phone EMI. The FDA has
tested hearing aids for interference from
