U.S. FDA
Although the existing scientific data do not justify FDA regulatory actions at 
this time, FDA has urged the mobile phone industry to take a number of steps 
to assure public safety. The agency has recommended that the industry:
• Support needed research into possible biological effects of RF of the type 
emitted by mobile phones;
• Design mobile phones in a way that minimizes any RF exposure to the user 
that is not necessary for device function; and
• Cooperate in providing mobile phone users with the best possible 
information on what is known about possible effects of mobile phone use 
on human health.
At the same time, FDA belongs to an interagency working group of the federal 
agencies that have responsibility for different aspects of mobile phone safety 
to ensure a coordinated effort at the federal level. These agencies are:
• National Institute for Occupational Safety and Health
• Environmental Protection Agency
• Federal Communications Commission
• Occupational Health and Safety Administration
• National Telecommunications and Information Administration
The National Institutes of Health also participates in this group.
In the absence of conclusive information about any possible risk, what can concerned 
individuals do?
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 people are concerned about avoiding 
even potential risks, there are simple steps they can take to do so. For 
example, time is a key factor in how much exposure a person receives. Those 
persons who spend long periods of time on their hand-held mobile phones 
could consider holding lengthy conversations on conventional phones and 
reserving the hand-held models for shorter conversations or for situations 
when other types of phones are not available.
