• National Telecommunications and Information Administration
The National Institutes of Health participates in some interagency working group 
activities, as well.
FDA shares regulatory responsibilities for wireless phones with the Federal 
Communications Commission (FCC). All phones that are sold in the United States 
must comply with FCC safety guidelines that limit RF exposure. FCC relies on FDA 
and other health agencies for safety questions about wireless phones.
FCC also regulates the base stations that the wireless phone networks rely upon. 
While these base stations operate at higher power than do the wireless phones 
themselves, the RF exposures that people get from these base stations are typically 
thousands of times lower than those they can get from wireless phones. Base stations 
are thus not the primary subject of the safety questions discussed in this document.
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 
radiofrequency 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 the 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 radiofrequency 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 radiofrequency
