국내·외 NORM 취급 산업 규제 기준 및 방사선학적 특성 분석 = Analysis of Regulation Standard and Radiological Characteristics of NORM Industry

다국어 초록 (Multilingual Abstract)

International organizations such as IAEA and EC recommend graded approach by identifying NORMindustries requiring radiation protection. In Korea, single regulation rather than graded regulation for NORM industryis applied. Therefore, it consumes more manpower and costs than necessary for both regulators and workers, and isnot optimized. The purpose of this study is to analyze domestic and foreign NORM industry regulatory standards andradiological characteristics for graded approach of NORM industry in Korea. Safety reports and publications such asSRS 49 and ICRP 142 published by international organizations were investigated, and domestic and foreign NORMregulatory guidelines and legislation such as Health Canada and the Act on Protective Action Guidelines AgainstRadiation in the Natural Environment were investigated to indicate NORM industries and regulatory standards.
The radioactivity concentration of raw materials or by-products, radiation dose by industrial process of the NORMindustry identified in IAEA and Korea were investigated. Nine NORM industries in Korea were identified based onthe NORM industry from IAEA and KINS survey report. Foreign countries such as Canada, UK and Denmark wereexecuting graded approach such as classification of dose level or licensing, registration, notification based on safetyassessment. Radioactivity concentration of domestic and foreign NORM industries were widespread up to 200 Bq g-1or higher based on industrial process and work type, and numerous NORM industries that exceeded radiation doseof 1 mSv y-1were indicated. Therefore, it is necessary to consider handling materials and work types of identifiedNORM industry when establishing graded approach for NORM industry in Korea considering domestic situation.
The results of this study are expected to be used as basic data for developing methodology of graded approach forNORM industry in Korea.
