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?
