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.
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.
