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
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.
