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:
