Health and Safety Information 123
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 and Development Agreement (CRADA) to do 
research on wireless phone safety. FDA provides the 
scientific oversight, obtaining input from experts in 
government, industry, and academic organizations. 
CTIA-funded research is conducted through contracts 
to independent investigators. The initial research will 
include both laboratory studies and studies of 
wireless phone users. The CRADA will also include a 
broad assessment of additional research needs in the 
context of the latest research developments around 
the world.
What steps can I take to reduce my exposure to
radio frequency energy from my wireless
phone?
If there is a risk from these products - and at this 
point we do not know that there is - it is probably 
very small. But if you are concerned about avoiding 
even potential risks, you can take a few simple steps 
to minimize your exposure to radio frequency energy 
(RF). 
Since time is a key factor in how much exposure a 
person receives, reducing the amount of time spent 
using a wireless phone will reduce RF exposure.
