Health and Safety Information 72

wireless phones can expose the user to measurable

radio frequency energy (RF) because 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.

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 radio frequency energy (RF) in the

microwave range while being used. They also emit

very low levels of RF when in the stand-by 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.

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 radio frequency 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 the type 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
