(RF) energy exposures characteristic of wireless phones have
yielded confl icting 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
