Radio Frequency Radiation Hazard Survey 141 Tactical Control System Ramey PR

摘要

At the request of 156th TAC Clinic Bioenvironmental Engineer, AFOEHL personnelsurveyed radio frequency radiation (RFR) hazards from the AN/TPS-43E transportable radar at the 141st Tactical Control Squadron, Ramey PR. During the survey, final installation checks were being performed on a new AN/FPS-93 radar, so a RFR hazard survey was performed on that unit as well. Measurements showed no hazard from either radar while the antennas are rotating. The AN/TPS-43E is mechanically interlocked so it will not radiate while the antenna is stopped. Operating instructions should specify immediate deactivation of the radar transmitter in case of interlock failure. The AN/FPS-93 will produce a hazard if the transmitter is operated while the antenna is stopped. The hazardous area is along the beam axis and is only accessible by persons climbing on the interior or exterior of the radome, or on the antenna structure itself. The unit Radiation Safety Officer should be notified when individuals are working on or in the radome to assure that they are not exposed to the direct beam of the radar. In the future, an AN/FPS-6 radar will be installed at the site. A theoretical evaluation is included which should be verified by direct measurement when operational. (JHD)
