exposures, since the average period of phone use in these 
studies was around three years.

What research is needed to decide whether RF exposure 
from wireless phones poses a health risk ?

A combination of laboratory studies and 
epidemiological studies of people actually using wireless 
phones would provide some of the data that are needed. 
Lifetime animal exposure studies could 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 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).
