Safety Guidelines
measures like those described above to reduce your RF
exposure from wireless device use.
10. What about children using wireless devices?
The scientific evidence does not show a danger to users
of wireless devices, 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 devices. Reducing
the time of wireless device 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 devices 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
device causes brain tumors or other ill effects. Their
recommendation to limit wireless device use by children was
strictly precautionary; it was not based on scientific evidence
that any health hazard exists.
11. What about wireless device interference with medical
equipment?
Radiofrequency energy (RF) from wireless devices 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 devices.
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 device EMI. The FDA has
tested hearing aids for interference from handheld wireless
devices and helped develop a voluntary standard sponsored
