12. 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.
public from harmful radiation emissions from these consumer products.
13. 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

14. Does the FCC maintain a database that includes information on
the location and technical parameters of all the transmitting
towers it regulates?
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

stations.) The FCC issues two types of licenses: site specific and market
