Consumer Information on Wireless Phones
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).
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.
