any harmful health effects from wireless phone RF
exposures.
However, none of the studies can answer questions
about longterm exposures, since the average period
of phone use in these studies was around three years.
5. What research is needed to decide whether RF
exposure from wireless phones poses a health
risk?
A combination of laboratory studies and
epidemiological studies of people actually using
wireless phones would provide some of the data that
is 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 of 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
