저준위방사선은 인류에 있어서 정말로 나쁜 영향이 있는 것인지. ${\ulcorner}$가능한한 낮게${\lrcorner}$가 상식으로 되어 있는 원자력 세계에 감히 의문을 갖고 이 상식과는 다른 견해를 내세우는 연구자가 나오기 시작하고 있다. 그 연구나 사례는 그 역사나 데이터에서 오늘의 원자력계의 ${\ulcorner}$상식${\lrcorner}$을 타파하기 까지에는 이르지 않지만 하나의 사고 실험으로서는 흥미있는 내용으로 되어 있다.

원전으로부터 방사성물질의 외부방출로 인한 환경영향을 측정하고, 뜻하지 않은 사고시 환경에서의 이상징후를 조기에 알아보기 위해, 원자력발전소에서는 환경방사선 감시시스템을 설치$\cdot$운영하고 있다. 감시단말기는 $486DX_2$급으로 20인치 터치스크린 컬러 모니터로 하였고 단말기 조작을 쉽게 하기 위해 화면 터치, 마우스 사용, 키보드 사용 등 어느 것을 사용하여도 가능하도록 하여 누구나 쉽게 측정자료를 출력해 볼 수 있도록 하였다.

In this paper we studied the radiation detection technology which described the radiation level distribution in high radiation area with remotely and safely. The designed radiation mapping system was composed of radiation nodes and radiation station. The radiation nodes could sense the radiation dose values with pMOSFET radiation sensors and transmit them to the radiation station. At the radiation station the received radiation values were merged with a geometric information and visualized at the virtual graphic location. For the functional verification of the above system, we attached the radiation nodes to each corner in our laboratory, executed the mapping tests, and confirmed the designed functions finally.

The purpose of this study is to provide basic data for policy making by understanding preparation plans and awareness of nuclear accidents and radiation terrorism among police officers in the vicinity of nuclear power plants. 221 police officers working in Busan metropolitan city were surveyed and their perception of disaster response was analyzed by organizational structure, command ability, and opinion management. As a result, there was no significant difference in disaster response perception by gender and command class (p>.05). There was statistically significant difference in the ability of command in age and ability according to work experience. As a result of the correlation analysis, there were statistically significant correlations among the three items of organizational structure perception, command ability, and opinion management (+0.5) (p<.01). Overall, it was positive for the police system, and it was well aware of the police work in case of radiation accidents and terrorist attacks. The purpose of this study is to provide basic data for policy making by understanding the coping and awareness of nuclear accidents and radiation terrorism among police officers in the vicinity of nuclear power plants.

Brachytherapy is generally performed in conjunction with external radiation therapy, and the treatment course is very complicated, which can lead to radiation accidents. In order to solve this problem, we designed the process map by applying the failure mode and effects analysis (FMEA) method to the Brachytherapy and scored the risk priority number (RPN) for each treatment course based on this process map. The process map consisted of five steps, Patient consulting", "Brachytherapy simulation", "CT simulation", "Brachytherapy treatment planning" and "Treatment". In order to calculate the RPN, doctor, medical physicist, dose planners, therapist, and nurse participated in the study and evaluated occurrence, severity, and lack of detectability at each detail step. Overall, the process map is preceded by a patient identification procedure at each treatment stage, which can be mistaken for another patient, and a different treatment plan may be established to cause a radiation accident. As a result of evaluating the RPN for the detailed steps based on the process map, overall "Patient consulting" and "Brachytherapy treatment planning" step were evaluated as high risk. The nurses showed a tendency to be different from each other, and the nurses had a risk of 55 points or more for all the procedures except "Treatment", and the "Brachytherapy simulation" step was the highest with 88.8 points. Since the treatment stage differs somewhat for each medical institution performing radiotherapy, it is thought that the risk management should be performed intensively by preparing the process map for each institution and calculating the risk RPN.

목적 : 미국 NRC 의 위험도 평가 방법론(NUREG/CR-6642)에 국내에서 시행되는 고선량율 근접치료의 표준입력 자료를 대입하여 고선량율 근접치료시 위험도를 정량적으로 산출하고 그 값을 비교하고자 한다. 대상 및 방법 : 고선량율 근접치료 시스템에 대한 위험도 평가를 위해 국내에서 고선량율 근접치료를 시행하고 있는 17개 의료기관으로부터 방사성동위원소의 설치와 폐기시의 방사능, 선원의 유형, 연간 총 치료회수 등 기초 자료를 수집하였다. 이로부터 방사성동위원소의 평균세기 연간 치료회수 등을 미국 NRC의 위험도 평가 방법론의 데이터베이스에 입력하여 고선량율 근접치료의 직무별, 피폭인의 종류, 정상상태와 사고 등의 형태에 따라 그 위험도를 구하였다. 결과 : 국내 고선량율 근접치료의 위험도는 미국 NRC의 위험도 평가 방법론에 따른 데이터베이스의 입력 결과 일반인의 정상상태와 사고 그리고 방사선종사자의 정상상태와 사고 시에 따라 그 위험도가 1.52-01, 2.96-03, 8.64-01, 3.32-02 rem/yr로 산출되었고 그 값을 미국 NRC의 값과 비교하였다. 결론 : 고선량율 근접치료 시 미국 NRC의 위험도 결과보다는 국내의 경우 수배 정도 높게 계산되었고 일반인과 방사선종사자, 정상상태와 사고, 직무별 패턴 등은 동일한 것으로 간주된다.
