Safety

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 difﬁculties in measuring

actual RF exposure during day-to-day use

of wireless phones. Many factors affect

this measurement, such as the angle at
