U.S. FDA

The U.S. Food and Drug
Administration's (FDA) Center
for Devices and Radiological
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 know – 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,
U.S. FDA
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 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 antenna – the primary
source of the RF – and the person's
head. The exposure to RF from
mobile phones in which the antenna
is located at greater distances from
the user (on the outside of a car, for
example) is drastically lower than
that from hand-held phones,
because a person's RF exposure
decreases rapidly with distance from
the source. The safety of so-called
"cordless phones", which have a
base unit connected to the
telephone wiring in a house and
which operate at far lower power
levels and frequencies, has not been
questioned.
