• 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,
