Safety Guidelines
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?
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 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 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
