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 radiofrequency energy (i.e., 
radiofrequency radiation) in the microwave range while being 
used. They also emit very low levels of radiofrequency 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
