Safety Guidelines
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?
R adio 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
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 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
'compatible' hearing aid at the same time.
This standard was approved by the IEEE in
2000. The FDA continues to monitor the use
of wireless phones for possible interactions
with other medical devices. Should harmful
interference be found to occur, the FDA will
conduct testing to assess the interference
and work to resolve the problem.
