user, the exposure to RF is drastically lower because a person's RF exposure decreases rapidly with
increasing distance from the source. The so-called “cordless phones,” which have a base unit connected
to the telephone wiring in a house, typically operate at far lower power levels, and thus produce RF
exposures far below the FCC safety limits.
4. 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 (RF) energy
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 do not 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 phone RF exposures. However, none of the studies can answer
questions about long-term exposures, since the average period of phone use in these studies was
around three years.
5. What research is needed to decide whether RF exposure from wireless phones poses a health risk?
A combination of laboratory studies and epidemiological studies of people actually using wireless
phones would provide some of the data that are needed. Lifetime animal exposure studies could be
completed in a few years. However, very large numbers of animals would be needed to provide reliable
proof of a cancer promoting effect, if one exists. Epidemiological studies can provide data that is
directly applicable to human populations, but ten or more years follow-up may be needed to provide
