The various FCC Bureaus also publish on at least a weekly basis, bulk extracts of their licensing
databases. Each licensing database has its own unique file structure. These extracts consist of
multiple, very large files. The FCC's Office of Engineering and Technology (OET) maintains an
index to these databases at http://www.fcc.gov/oet/info/database/fadb.html. Entry points into the
various databases include frequency, state/county, latitude/longitude, call-sign and licensee
name. For further information on the Commission's existing databases, you can contact Donald
Campbell at dcampbel@fcc.gov or 202-418-2405.
Can local and state governmental bodies establish limits for RF exposure?
Although some local and state governments have enacted rules and regulations about human
exposure to RF energy in the past, the Telecommunications Act of 1996 requires the Federal
Government to control human exposure to RF emissions. In particular, Section 704 of the Act
states that, "No State or local government or instrumentality thereof may regulate the
placement, construction, and modification of personal wireless service facilities on the basis of
the environmental effects of radio frequency emissions to the extent that such facilities comply
with the Commission's regulations concerning such emissions." Further information on federal
authority and FCC policy is available in a fact sheet from the FCC's Wireless Telecommunications
Bureau at www.fcc.gov/wtb.
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 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.
