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.

8. 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.

9. Which other federal agencies have responsibilities

related to potential RF health effects?

Additional information on the safety of RF exposures from

various sources can be obtained from the following

organizations.
