individual would essentially have to remain in the main transmitted

radio signal (at the height of the antenna) and within a few feet from

the antenna. This is, of course, very unlikely to occur.

When cellular and PCS antennas are mounted on rooftops, RF levels

on that roof or on others near by would probably be greater than those

typically encountered on the ground. However, exposure levels

approaching or exceeding safety guidelines should be encountered

only very close to or directly in front of the antennas. In addition, for

sector-type antennas, typically used for such rooftop base stations, RF

levels to the side and in back of these antennas are insignificant.

General guidelines on antenna installations and circumstances that

might give rise to a concern about a facility's conformance with FCC

regulations can be found in A Local Government Official's Guide to

Transmitting Antenna RF Emission Safety: Rules, Procedures, and

Practical Guidance. This Guide can be accessed at: http://

www.fcc.gov/oet/rfsafety.

Who regulates exposure to radiation from microwave ovens,

television sets and computer monitors?

The Food and Drug

Administration is responsible for protecting the public from harmful

radiation emissions from these consumer products.

Does the FCC routinely monitor radiofrequency radiation from

antennas?

The FCC does not have the resources or the personnel

to routinely monitor the emissions for all the thousands of

transmitters that are subject to FCC jurisdiction. However, the FCC

does have measurement instrumentation for evaluating RF levels in

areas that may be accessible to the public or to workers. If there is

evidence for potential non-compliance with FCC exposure guidelines

for a FCC-regulated facility, staff from the FCC's Office of Engineering

and Technology or the FCC Enforcement Bureau can conduct an

investigation, and, if appropriate, perform actual measurements.

Circumstances that could give rise to a concern about a facility's

conformance with FCC regulations can be found in A Local

Government Official's Guide to Transmitting Antenna RF Emission

Safety: Rules, Procedures, and Practical Guidance. This Guide can be

accessed at: http://www.fcc.gov/oet/rfsafety. Potential exposure

problems should be brought to the FCC's attention by contacting the

FCC RF Safety Program at: 202-418-2464 or by email:

[email protected].

Does the FCC maintain a database that includes information on

the location and technical parameters of all the transmitting

towers it regulates?

Each of the FCC Bureaus maintains its own

licensing database system for the service(s) it regulates (e.g.,

television, cellular service, satellite earth stations.) The FCC issues

two types of licenses: site specific and market based. In the case of

site specific licensed facilities, technical operating information is

collected from the licensee as part of the licensing process. However,

in the case of market based licensing (e.g., PCS, cellular), the

licensee is granted the authority to operate a radio communications

system in a geographic area using as many facilities as are required,

and the licensee is not required to provide the FCC with specific

location and operating parameters of these facilities.

Information on site specific licensed facilities can be found in the

“General Menu Reports” (GenMen) at http://gullfoss2.fcc.gov/cgi-bin/

ws.exe/genmen/index.hts.

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 [email protected] 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.
