Section 4A: Safety Guidelines 171or near the FCC limits for cellular or PCS frequencies an individual wouldessentially have to remain in the main transmitted radio signal (at the height ofthe antenna) and within a few feet from the antenna. This is, of course, veryunlikely to occur.When cellular and PCS antennas are mounted on rooftops, RF levels on that roofor on others near by would probably be greater than those typically encounteredon the ground. However, exposure levels approaching or exceeding safetyguidelines should be encountered only very close to or directly in front of theantennas. In addition, for sector-type antennas, typically used for such rooftopbase stations, RF levels to the side and in back of these antennas are insignificant.General guidelines on antenna installations and circumstances that might giverise to a concern about an facility's conformance with FCC regulations can befound in A Local Government Official's Guide to Transmitting Antenna RFEmission Safety: Rules, Procedures, and Practical Guidance. This Guide can beaccessed at: http://www.fcc.gov/oet/rfsafety.Who regulates exposure to radiation from microwave ovens, televisionsets and computer monitors?The Food and Drug Administration is responsible for protecting the publicfrom harmful radiation emissions from these consumer products.Does the FCC routinely monitor radiofrequency radiation fromantennas?The FCC does not have the resources or the personnel to routinely monitor theemissions for all the thousands of transmitters that are subject to FCCjurisdiction. However, the FCC does have measurement instrumentation forevaluating 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 guidelinesfor a FCC-regulated facility, staff from the FCC's Office of Engineering andTechnology or the FCC Enforcement Bureau can conduct and investigation,and, if appropriate, perform actual measurements. Circumstances that couldgive rise to a concern about an facility's conformance with FCC regulations canbe found in A Local Government Official's Guide to Transmitting Antenna RFEmission Safety: Rules, Procedures, and Practical Guidance. This Guide can beaccessed at: http://www.fcc.gov/oet/rfsafety. Potential exposure problems shouldbe brought to the FCC's attention by contacting the FCC RF Safety Program at:202-418-2464 or by email: rfsafety@fcc.gov.Does the FCC maintain a database that includes information on thelocation and technical parameters of all the transmitting towers itregulates?Each of the FCC Bureaus maintains its own licensing database system for theservice(s) it regulates (e.g., television, cellular service, satellite earth stations.)The FCC issues two types of licenses: site specific and market based. In thecase of site specific licensed facilities, technical operating information iscollected from the licensee as part of the licensing process. However, in thecase of market based licensing (e.g., PCS, cellular), the licensee is granted theauthority to operate a radio communications system in a geographic area using
