safety guidelines that were developed with
the advice of the FDA and other federal
health and safety agencies. When the
phone is located at greater distances from
the 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.
