SAFETY
of the short distance between the phone and the user's head. These RF exposures
are limited by Federal Communications Commission safety guidelines that were
developed with the advice of FDA and other federal health and safety agencies.
When the phone is located at greater distances from the user, the exposure to RF is
drastically lower because a person's RF exposure decreases rapidly with increasing
distance from the source. The so-called "cordless phones", which have a base unit
connected to the telephone wiring in a house, typically operate at far lower power
levels, and thus produce RF exposures well within the FCC's compliance limits.
2. Do wireless phones pose a health hazard?
The available scientific evidence does not show that any health problems are
associated with using wireless phones. There is no proof, however, that wireless
phones are absolutely safe. Wireless phones emit low levels of radiofrequency
energy (RF) in the microwave range while being used. They also emit very low
levels of RF when in the standby 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.

3. What is FDA's role concerning the safety of wireless phones?
Under the law, 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 radiofrequency energy (RF) at a level that is
hazardous to the user. In such a case, 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 do not justify FDA regulatory actions, FDA
has urged the wireless phone industry to take a number of steps, including the
following:
• Support needed research into possible biological effects of RF of thetype emitted
by wireless phones;
• Design wireless phones in a way that minimizes any RF exposure to the user that
is not necessary for device function; and
• Cooperate in providing users of wireless phones with the best possible
information on possible effects of wireless phone use on human health
FDA belongs to an interagency working group of the federal agencies that have
responsibility for different aspects of RF safety to ensure coordinated efforts at the
federal level. The following agencies belong to this working group:
