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 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.
