For Your Safety
There is no proof, however, that
wireless phones are absolutely
safe. Wireless phones emit low
levels of Radio Frequency (RF)
energy in the microwave range
while being used. They also emit
very low levels of RF when in idle
mode. Whereas high levels of RF
can produce health effects (by
heating tissue), exposure to low
level RF that does not produce
heating effects causes no known
adverse health effects. Many
studies of low level RF exposures
have not found any biological
effects. Some studies have
suggested that some biological
effects may occur, but such
findings have not been confirmed
by additional research. In some
cases, other researchers have had
difficulty in reproducing those
studies, or in determining the
reasons for inconsistent results.

2. What is the FDA's role
concerning the safety of
wireless phones?
Under the law, the FDA does not
review the safety of radiation-
emitting consumer products
such as wireless phones before
they can be sold, as it does
with new drugs or medical
devices. However, the agency has
authority to take action if wireless
phones are shown to emit Radio
Frequency (RF) energy at a level
that is hazardous to the user.
In such a case, the FDA could
require the manufacturers of
wireless phones to notify users of
the health hazard and to repair,
replace, or recall the phones so
that the hazard no longer exists.
Although the existing scientific
data does not justify FDA
regulatory actions, the FDA has
urged the wireless phone industry
to take a number of steps,
including the following:
