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.
6. What is the FDA doing to find out more about the possible health
effects of wireless phone rF?
the Fda is working with the u.s. National toxicology Program
and with groups of investigators around the world to ensure that
high priority animal studies are conducted to address important
questions about the effects of exposure to radiofrequency energy
(rF). the Fda has been a leading participant in the World Health
organization international electromagnetic Fields (eMF) Project
since its inception in 1996. An influential result of this work has
been the development of a detailed agenda of research needs that
has driven the establishment of new research programs around
the world. the project has also helped develop a series of public
information documents on eMF issues. the Fda and the cellular
telecommunications & internet association (ctia) have a formal
cooperative research and development agreement (crada)
to do research on wireless phone safety. the Fda provides the
scientific oversight, obtaining input from experts in government,
