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
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
