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.

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
