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 devices 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 devices, so we do not 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 devices
and primary brain cancer, glioma, meningioma, or
acoustic neuroma, tumors of the brain or salivary
22
gland, leukemia, or other cancers. None of the
studies demonstrated the existence of any harmful
health effects from wireless device RF exposures.
However, none of the studies can answer questions
about long-term exposures, since the average
period of device use in these studies was around
three years.
5. What research is needed to decide whether
RF exposure from tablets poses a health
risk?
A combination of laboratory studies and
epidemiological studies of people actually using
tablets would provide some of the data that are
needed. Lifetime animal exposure studies could
be completed in a few years. However, very large
numbers of animals would be needed to provide
reliable proof of a cancer promoting effect if one
exists. Epidemiological studies can provide data
that is directly applicable to human populations,
but ten or more years follow-up may be needed to
provide answers about some health effects, such
as cancer. This is because the interval between
the time of exposure to a cancer-causing agent
and the time tumors develop — if they do —
may be many, many years. The interpretation of
epidemiological studies is hampered by difficulties
in measuring actual RF exposure during day-
to-day use of tablets. Many factors affect this
