Abstract

In this paper, we propose Total RMS(Radiation Monitoring System) for nuclear and nuclear medicine. The proposed system can expand and control Stack Monitor, Area Monitor, and Water(Liquid) Monitor into one system, and can monitor the signals measured by each radiation detector in an integrated manner. The proposed system consists of a sensor module that detects the radiation, a display unit that displays the radiation dose near the radiation detection location, an alarm unit that reports the alarm when the detected radiation dose reaches the danger level, A Main Hub for collecting and storing the contents to the remote monitoring system, and an RMS Monitoring Unit for clearly displaying the measured radiation dose at the remote site. In order to evaluate the performance of Total RMS for the proposed nuclear and nuclear medicine field, it is confirmed that the measurement uncertainty is less than 8.5% and it operates normally within ${\pm}15%$ of the international standard.

본 논문에서는 원자력 및 핵의학 분야용 Total RMS(Radiation Monitoring System)를 제안한다. 제안하는 시스템은 Stack Monitor, Area Monitor, Water(Liquid) Monitor 등을 하나의 시스템으로 확장 및 제어할 수 있는 장비로 각 방사선 검출기에서 측정된 신호를 통합 모니터링 할 수 있다. 제안하는 시스템은 해당 방사선을 검출하는 Sensor Module, 방사선 검출 위치에 인접한 곳에서 방사선량을 디스플레이 하는 Display Unit, 검출된 방사선량이 위험 수준에 도달시 경보를 알리는 Alarm Unit, 각 모니터링에서 측정된 방사선량들을 취합하고 저장하여 원격 감시 시스템에 내용을 전달하는 Main Hub, 원격지에서 측정된 방사선량 상태를 일목요연하게 디스플레이 하는 RMS Monitoring Unit 등으로 구성된다. 제안된 원자력 및 핵의학 분야용 Total RMS의 성능을 평가하기 위하여 공인시험기관에서 실험한 결과, 측정 불확도가 8.5%이하로 측정되어 국제 표준인 ${\pm}15%$ 이하에서 정상동작 됨이 확인되었다.
