Health Consumer Update on Mobile
Phones

FDA has been receiving inquiries about the safety of mobile
phones, including cellular phones and PCS phones. The
following summarizes what is known—and what remains
unknown—about whether these products can pose a hazard to
health, and what can be done to minimize any potential risk. This
information may be used to respond to questions.

Why the concern?

Mobile phones emit low levels of radio frequency energy (i.e.,
radio frequency radiation) in the microwave range while being
used. They also emit very low levels of radio frequency energy
(RF), considered non-significant, when in the stand-by mode. It is
well known that high levels of RF can produce biological damage
through heating effects (this is how your microwave oven is able
to cook food). However, it is not known whether, to what
extent, or through what mechanism, lower levels of RF might
cause adverse health effects as well. Although some research has
been done to address these questions, no clear picture of the
biological effects of this type of radiation has emerged to date.
Thus, the available science does not allow us to conclude that
mobile phones are absolutely safe, or that they are unsafe.
However, the available scientific evidence does not demonstrate
any adverse health effects associated with the use of mobile
phones.

What kinds of phones are in question?

Questions have been raised about hand-held mobile phones, the
kind that have a built-in antenna that is positioned close to the
user's head during normal telephone conversation. These types
