Abstract

In this paper, we proposed the development of a mixed sensor parts for integrated radiation exposure protection fireman's life-saving alarm that can be location-tracked and irradiated. To measure radiation exposure dose, we use the PIN-Diode radiation measurement sensor module, a semi-conductive radiation measurement sensor that can minimize size and weight. The design for removing leakage current is carried out to enhance the characteristics of the radiation measurement sensor using PIN-Diode. The IMU sensor module is used to estimate the location of the current fireman at the same time as the accident estimate by adding together the data and the values for acceleration on the three axis. Experiments were conductied by an authorized testing agency to determine the efficiency of the proposed mixed sensor parts for integrated radiation exposure protection fireman's life-saving alarms. The cumulative dose measurement range was measured in the range of 10 μSv to 10 mSv, the highest level in the world. The accuracy was measured from ±6.3% to ±9.0% (137 Cs) and normal operation was found at the international standard of ±15%. In addition, positional accuracy was measured within ±10%, resulting in a high level of results, demonstrating its effectiveness. Therefore, it is expected that more firemen will be able to provide with superior performance integrated radiation exposure protection fireman life-saving alarm.

본 논문에서는 위치추적과 방사선 측정이 가능한 일체형 방사선 피폭 방호 소방관 인명구조 경보기의 혼합형 센서부 개발을 제안한다. 방사선피폭선량을 측정하기 위하여 크기와 무게를 최소화 할 수 있는 반도체형 방사선 측정 센서인 PIN-Diode 방사선 측정 센서모듈을 사용한다. PIN-Diode 방식의 방사선 측정 센서 특성을 높이기 위하여 누설전류를 제거하기 위한 설계를 수행한다. IMU 센서모듈을 사용하여 3축에 대한 데이터와 가속도에 대한 수치를 합산하여 사고추정과 동시에 현재 소방관의 위치를 추정한다. 제안된 일체형 방사선 피폭 방호 소방관 인명구조 경보기를 위한 혼합형 센서부의 효율을 판단하기 위하여 공인시험기관에서 실험하였다. 누적선량 측정범위는 세계 최고 수준인 10μSv~10mSv 범위에서 측정이 되었다. 정확도는 ±6.3%~±9.0%(137Cs) 측정 불확도가 측정되어 국제 표준인 ±15% 이하에서 정상동작 됨이 확인되었다. 또한 위치정확성은 ±10% 이내로 측정되어 높은 수준의 결과가 도출되어 그 효용성이 입증되었다. 따라서 보다 많은 소방관에게 성능이 우수한 일체형 방사선 피폭 방호 소방관 인명구조 경보기 보급이 될 수 있으리라 기대된다.
