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 diffi culties 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

infl uential result of this work has been the development of a detailed agenda of
