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.
12. Which other federal agencies have responsibilities related to potential RF health
effects?
