Health and safety information
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 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.
10. What are the results of the research done already?
The research done thus far has produced conflicting
results, and many studies have suffered from flaws in
their research methods. Animal experiments
investigating the effects of radio frequency energy
(RF) exposures characteristic of wireless phones have
yielded conflicting results that often cannot be
repeated in other laboratories. A few animal studies,
however, have suggested that low levels of RF could
accelerate the development of cancer in laboratory
animals. However, many of the studies that showed
increased tumor development used animals that had
been genetically engineered or treated with cancer
causing chemicals so as to be pre-disposed to develop
cancer in the absence of RF exposure. Other studies
exposed the animals to RF for up to 22 hours per day.
These conditions are not similar to the conditions
under which people use wireless phones, so we don t
know with certainty what the results of such studies
mean for human health.
Three large epidemiology studies have been published
since December 2000. Between them, the studies
investigated any possible association between the use
of wireless phones and primary brain cancer, gioma,
meningioma, or acoustic neuroma, tumors of the brain
or salivary gland, leukemia, or other cancers. None of
