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
