with the best possible information on what is

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:

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.
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 antenna is located

package, or

Again, the scientific data do not demonstrate that
mobile phones are harmful. But if people are
concerned about the radiofrequency energy from
these products, taking the simple precautions
outlined above can reduce any possible risk.
