can be sold, as it does with new drugs or medical devices. 
However, the agency has authority to take action if wireless 
phones are shown to emit radio frequency energy (RF) at a level 
that is hazardous to the user. In such a case, FDA could require 
the manufacturers of wireless phones to notify users of the 
health hazard and to repair, replace or recall the phones so that 
the hazard no longer exists.
Although the existing scientific data do not justify FDA regulatory 
actions, FDA has urged the wireless phone industry to take a 
number of steps, including the following:
• 
Support needed research into possible biological effects of RF of the 
type emitted by wireless phones;
• 
Design wireless phones in a way that minimizes any RF exposure to 
the user that is not necessary for device function; and
• 
Cooperate in providing users of wireless phones with the best possible 
information on possible effects of wireless phone use on human 
health.
FDA belongs to an interagency working group of the federal 
agencies that have responsibility for different aspects of RF 
safety to ensure coordinated efforts at the federal level. The 
following agencies belong to this working group:
• 
National Institute for Occupational Safety and Health 
• 
Environmental Protection Agency
• 
Federal Communications Commission
• 
Occupational Safety and Health Administration
• 
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 are the results of the research done already?
The research done thus far has produced conflicting results, and 
many studies have suffered from flaws in their research 
methods. Animal experiments investigating the effects of radio 
frequency energy (RF) exposures characteristic of wireless 
phones have yielded conflicting results that often cannot be
