Radiation workers working in nuclear medicine department are exposed to radiation, especially in extremities and the eye lens, due to their work consisting of distributing radioactive isotopes and injecting patients with the radiological materials. The assessment of radiological exposure to the extremities and the eye lens using whole body effective dose assessment method cannot be deemed valid; Because the extremities and the eye lens cannot be constantly protected, there needs to be another dose assessment method. Despite the apparent error in the current assessment method, radiation workers in nuclear medicine department overlook exposure to radiation in the extremities and the eye lens, leading to the current lack of exposure dose control. As such, we set out to understand the radiation workers’ level of knowledge and awareness in this issue by surveying 33 radiation workers working in Korean nuclear medicine department. As for the level of knowledge about the dosimeter for extremities and the eye lens, most radiation workers were aware that radiation exposure in the extremities and the eye lens took place during their work, as well as yearly exposure dose limit, but they were not as knowledgeable about the dosimeter. In the assessment of the radiation workers’ awareness of dosimeter, these professionals acknowledged the necessity of wearing a dosimeter to manage the exposure dose in the extremities and the eye lens, although their level of understanding and trust for these products were rather low. In the current usage of dosimeters in nuclear medicine department, it was revealed that most radiation workers do not wear dosimeters during their work, which led to the lack of exposure dose assessment during distribution and injection tasks. As such, the current study concludes that policies on exposure dose measurement and assessment are required to optimize the amount of exposure to the extremities and the eye lens in radiation workers, in addition to continued education and training to change awareness about controlling the exposure dose.

본 연구의 목적은 방사선의 사업적 이용에 따른 방사선발생장치 또는 방사성동위원소 등(이하 방사성동위원소 등)을 운용하는 방사선작업종사자를 대상으로 방사선안전관리와 관련된 지식의 설문 조사하고 이를 체계적으로 추이분석 함으로서 방사선 이용시설 등의 방사선안전 문화를 정착시키기 위함에 있다. 연구 방법은 2011년 08월 01일 부터 09월 05일 까지 861 명의 방사선 종사자를 대상으로 설문 조사를 하였다. 분석 방법으로 설문 응답자의 일반적인 특성과 기관정보는 빈도 분석을 하였으며 방사선안전관리에 대한 지식 수준은 평균과 표준편차를 구하여 각각 비교하였다. 분석 결과 작업 종사자의 방사선 안전 관리에 대한 지식 조사에서는 종사자 모두 높은 수준으로 평가 되었다. 결론적으로 방사선 작업종사자들의 방사선 안전관리와 관련하여 보다 다양한 요인들에 대한 연구들이 수행되어야 하며 작업종사자들의 의식을 높이기 위해서 시기적절한 교육이 필요할 것으로 사료되며, 지속적으로 방사선 작업종사자들을 관리함으로써 효율적인 방사선이용이 될 수 있는 기반이 확립될 것으로 사료된다. The purpose of this study was examine via a survey the knowledge related to radiation safety management (RSM) among radiation workers who operated or used a radiation generator or radioactive isotopes (radioactive isotopes, etc. hereinafter) for industrial use and to systematically analyze the changes in the survey results in order to promote a radiation safety culture for facilities where radiation is used. We administered a questionnaire to 861 radiation workers in the period from August 1 to September 5, 2011. As for the analysis method, a frequency analysis was made for the general characteristics and organization information of survey respondents, while the average and standard deviation were calculated and compared for the knowledge level of the RSM. According to the analysis results, the knowledge level of the RSM was evaluated to be high in all of the radiation workers. In conclusion, it is required to conduct a study on various factors in regards to the RSM among radiation workers. This can contribute to establishing educational programs in a timely manner to increase the awareness of safe and efficient use of radioactive materials and equipments by radiation workers.
