Section 4A: Safety Guidelines 158
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 Sprint 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 Sprint 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. 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 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 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:

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., Sprint PCS, cellular), the licensee is
