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
