worker-centered safety management for hazardous areas in the plant is required. The causes of gas accidents in the past five years are closely related to the behavior of the operator, such as careless handling of the user, careless handling of the suppliers, and intentional, as well as equipment failure and accident of thought. In order to prevent such accidents, real-time monitoring of hazardous areas in the plant is required. However, when installing a camera in a work space for real-time monitoring, problems such as human rights abuse occur. In order to prevent this, an infrared camera with low resolution with low exposure of the operator is used. In real-time monitoring, image analysis is performed using CNN algorithm, not human, to prevent human rights violation.

Radioactive liquid waste generated during operation and overhaul is collected and reused through the radioactive liquid waste treatment system and continuous monitoring system in the nuclear power plant or discharged to the outside if it satisfies the limit within the control and monitoring. However, there are concerns about boric acid management, which controls the power output of nuclear power plants in radioactive liquid waste. Due to the behavior of boric acid, it is difficult to remove it in the existing liquid radwaste system, and the concentration of boric acid water discharged tends to be higher than the natural state of 5 ppm, so additional facilities should be considered. Therefore, this study aims to evaluate the radiological effects of radioactive waste treatment facilities that are under development and use them as a basis for managing worker exposure and evaluating the safety of facilities in the future.

This research, which was conducted for dental hygienists, intended to check out what factors have an influence on their behaviors by measuring the level of self-efficacy and consciousness on the use of radiation, knowledge and attitude on radiation safety management(RSM). The subjects were 235 of the dental hygienists and this study performed a survey 8 May to 17 June, 2011. The survey results were as follows. 1. As a result of comparing the average of the self-efficacy according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to health condition, protection facilities condition. 2. As a result of comparing the average of consciousness about radiation use according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to medical institute type, protection facilities conditions. 3. As a result of comparing the average of the behaviors for RSM according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to monthly income, medical institute type, whether or not education on radiation was conducted, the number of education, education type, and protection facilities condition. 4. As a result of analyzing what factors have an influence on the behaviors for RSM by employing the points of those behaviors as a dependent variable and self-efficacy, consciousness, knowledge and attitude as an independent variable in order to investigate those factors, it turned out that the factors which had a relatively larger influence on the point of behaviors were attitude and self-efficacy by that order(p<0.05). In conclusion, we believe that a variety of programs should be offered to provide knowledge on RSM as a prerequisite for improving the level of RSM behaviors by dental hygienists.

이 연구는 동위원소실에 근무하는 임상병리사들의 방사선 방어에 대한 지식, 태도 및 행위수준을 조사하여 상관관계를 파악하고 방사선 안전관리에 대한 행위에 영향을 미치는 요인을 분석하기 위해 시행하였다. 설문지는 2010년 10월부터 11월까지 대전 충청권 및 서울 경기권 동위원소실 임상병리사를 연구 대상자로 하여 연구자자 임의로 선정 직접설문, 또는 우편방식으로 조사하였고, 수집된 자료는 SPSS12.0 프로그램을 이용하여 빈도와 백분율, T-검정, ANOVA, 다중회귀분석법을 이용하여 분석하였다. 방사선 안전관리에 대한 지식 점수는 평균은 11.5점이었으며 표준편차는 ${\pm}$1.9 분포를 보였다. 방사선 안전관리에 대한 태도 점수는 평균 69.0점, 표준편차는 ${\pm}$5.4이었다. 방사선 방어에 대한 행위점수는 평균은 57.1점, 표준편차 ${\pm}$3.5이었다. 방사선 안전관리 행위에 있어 이론적으로 알고 있는 내용에 비해 수행이 현저히 떨어진 결과가 나왔으며, 방사선 안전관리에 대한 지식, 태도, 행위와의 상관성은 통계적으로 유의한 상관관계를 보였다(p<0.01). 행위점수에 영향을 미치는 요인으로는 종사자법정교육, RI 면허취득, 지식, 태도로 나타났다. 결론적으로 동위원소실에 근무하는 임상병리사의 방사성동위원소 안전관리 행위는 태도에 비하여 수행이 현저히 떨어진 결과가 나왔고, 안전관리 행위에 영향을 주는 인자로 종사자법정교육, RI 면허취득, 지식점수, 태도점수를 알 수 있었다. 업무 진행에 있어 잘못된 지식의 습득 및 태도를 취할 수 있는 가능성이 충분히 있으며 이를 바로 잡을 수 있도록 안전관리에 대한 지속적인 교육을 실시함과 더불어 RI면허 취득, 방사선 종사자에게 교육의 효과를 더욱 높이기 위한 적절한 교육 자료의 개발이 필요하다고 할 수 있다.
