Additional Health and Safety Information
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 of mobile phones are
of concern because of the short distance between the phone's
