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?
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
' c ompatible' phone and a ' c ompatible' 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.
