Section 4A: Safety Guidelines 177
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.
Which other federal agencies have responsibilities related to potential RF
health effects?
Certain agencies in the Federal Government have been involved in monitoring,
researching or regulating issues related to human exposure to RF radiation.
