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 studies investigated any possible association between the
use of wireless phones and primary brain cancer, glioma, meningioma, or
acoustic neuroma, tumors of the brain or salivary gland, leukemia, or other
cancers. None of the studies demonstrated the existence of any harmful health
effects from wireless phones RF exposures. However, none of the studies can
