Safety
between the use of wireless phones and
primary brain cancer, glioma, 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?
22
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
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
