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, 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
