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 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
