meningioma, or acoustic neuroma, tumors of the brain or salivary
gland, leukemia, or other cancers. None of the studies demonstrated
the existence of any harmful health effects from wireless phone RF
exposures. However, none of the studies can answer questions about
long-term 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 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
diffi culties 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.
