epidemiological studies of people actually
using wireless phones 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 10 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 wireless phones.
Many factors affect this measurement, such
as the angle at which the phone is held, or
which model of phone is used.
6. What is the FDA doing to find out
more about the possible health
effects of wireless phone RF?
The FDA is working with the U.S. National
Toxicology Program and with groups of
investigators around the world to ensure
that high priority animal studies are
conducted to address important questions
about the effects of exposure to radio
