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 scientic data does 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 scientic 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 radio frequency 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
leaets 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 scientic evidence
that any health hazard exists.
What about wireless phone interference with medical equipment?
Radio frequency 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 debrillators from wireless telephones.
This test method is now part of a standard sponsored by the Association for the Advancement of
Medical instrumentation (AAMI). The nal 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 debrillators 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 species 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, FDA will conduct testing to assess
the interference, and work to resolve the problem.
