Local radiation protection measurement network for TRIGA Reactor building

This system is intended for the protection of personal working in those areas of the reactor building where high gamma radiation fields are expected. A detector, sensitive to gamma radiation, is installed in each of the areas to be monitored. The detector will send a signal proportional to the radiation level in the area, to a corresponding electronic module (Alarm Unit), where the signal will be amplified and checked against alarm set-points for possible alarming condition. In case the field exceeds the alarm set-point, the Alarm Unit will produce a signal that will trigger the field alarms (Horn and Beacon), located in the area where that condition occurred. Each Alarm Unit will send a numerical input to central computer command. (authors)
