with the best possible information on possible
effects of wireless phone use on human health.
FDA belongs to an interagency working group of the
federal agencies that have responsibility for different
aspects of RF safety to ensure coordinated efforts at
the federal level. The following agencies belong to
this working group:
• “National Institute for Occupational Safety and
Health
• “Environmental Protection Agency
• “Federal Communications Commission
• “Occupational Safety and Health Administration
• “National Telecommunications and Information
Administration
The National Institutes of Health participates in
some interagency working group activities, as
well.FDA shares regulatory responsibilities for
wireless phones with the Federal Communications
Commission (FCC). All phones that are sold in the
United States must comply with FCC safety
guidelines that limit RF exposure. FCC relies on FDA
and other health agencies for safety questions about
wireless phones.FCC also regulates the base stations
that the wireless phone networks rely upon. While
these base stations operate at higher power than do
the wireless phones themselves, the RF exposures
that people get from these base stations are
typically thousands of times lower than those they
can get from wireless phones. Base stations are thus
not the primary subject of the safety questions
discussed in this document.
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 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
