FDA has been receiving inquiries about the safety of
mobile phones, including cellular phones and PCS
phones. The following summarizes what is know – and
what remains unknown – about whether these prod-
ucts 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 ener-
gy (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-signifi-
cant, 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 ov-
en 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
