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 radiofrequency
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
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 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 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.
