U.S. FDA

101

•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 Occupation- al Safety and Health

•Environmental Protection Agency

•Federal Communications Com- mission

•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 avail- able.

People who must conduct extended conversations in their cars every day could switch to a type of mobile phone that places more distance between their bodies and the source of the RF, since the exposure level drops off dramatically with distance. For example, they could switch to:

•a mobile phone in which the an- tenna is located outside the vehi- cle,

•a hand-held phone with a built-in antenna connected to a different antenna mounted on the outside of the car or built into a separate package, or

•a headset with a remote antenna to a mobile phone carried at the waist.
