* If you must conduct extended conversations by wireless phone every day, you could place more distance between
your body and the source of the RF, since the exposure level drops off dramatically with distance. For example, you
could use a headset and carry the wireless phone away from your body or use a wireless phone connected to a remote
antenna
Again, the scientific data do not demonstrate that wireless phones are harmful. But if you are concerned about the RF
exposure from these products, you can use measures like those described above to reduce your RF exposure from
wireless phone use.
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.
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
problem.
