Consumer Information on Wireless Phones
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
ten 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.
What is FDA doing to find out more about the possible
health effects of wireless phone RF?
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 radio frequency energy (RF).
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.
FDA and Cellular Telecommunications & Internet
Association (CTIA) have a formal Cooperative Research
