than the exposure levels recommended as safe by expert organizations. So

exposure to nearby residents would be well within safety margins.

Cellular and PCS base stations in the United States are required to comply with

limits for exposure recommended by expert organizations and endorsed by

government agencies responsible for health and safety. Measurements made

near cellular and PCS base station antennas mounted on towers have confirmed

that ground-level exposures are typically thousands of times less than the

exposure limits adopted by the FCC. In fact, in order to be exposed to levels at or

near the FCC limits for cellular or PCS frequencies an 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 an 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

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 and investigation, and,

if appropriate, perform actual measurements. Circumstances that could give

rise to a concern about an facility's conformance with FCC regulations can be

found in 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:
