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, 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 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. 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 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. FDA continues to
monitor the use of wireless phones for possible interactions with other
medical devices. Should harmful interference be found to occur, FDA will
conduct testing to assess the interference and work to resolve the
