Abstract

International Standardization in all technical area is gaining its momentum as its impact and implication over global trade is directly linked. The worldwide competition to secure a dominant position in the standardization process is ever growing over the years. In 2005, the International Technical Committee on Nuclear Instrumentation, which is a subunit of International Electro-technical Commission (IEC), was held in Korea under the auspices of MOST (Ministry of Science and Technology). Korea has adopted its Rule and Regulation as the National Standard. As a part of a link to National Mid-and Long-term Atomic Energy R&D Program of MOST, the technical development of a performance test for the radiation monitors was carried out under mechanical environment and electromagnetic immunity conditions. The characteristics of the radiation fields were also evaluated under the conditions and introduced to a techniques of performance test for the radiation protection instrumentation adopted IEC61526 standards and it's results was analyzed. We would like to share the experience gained in these efforts, failure as well as success, and to discuss the problems encountered and serious consideration to be taken into account in the future endeavor.

최근 국제 표준은 글로벌 패권확보 수단으로, 또 국제 무역의 중요 수단으로 여겨질 정도로 중요성이 커지고 있다. 특히 표준과 규제정책을 연계하며 국제 표준의 구속력을 강화하고 있는 추세에 있어, 나라마다 국제표준 선점을 두고 치열한 경쟁을 벌이고 있다. 세계 각국은 점차 규격을 IEC에 부응하는 방향으로 바꾸고 있으며 국내에서는 원자력 분야의 국제전기위원회 (International Electrotechnical Commission)기술위원회인 TC45(Nuclear Instrumentation) 총회를 2005년에 유치하여 국제적 활동을 강화하고 있으며 수 년 전부터 IEC 규격을 적용한 국가규격으로 대체하고 있는 실정이다. 여기에서는 원자력 중장기사업의 일환으로 "방사선계측기 성능평가 기술개발" 연구를 수행하여 물리적 및 전자기적 환경에서의 성능평가 기술 및 방사선장특성 평가 기술 개발을 수행하였으며 IEC61526(Radiation protection instrumentation)의 규격을 적용하여 개발된 방사선 방호용 계측기의 성능평가 기술을 소개하고 이러한 성능시험에서 얻어진 결과를 분석하여 방사선계측기를 개발할 때 고려하여야 할 사항과 현재 국내에서 사용 중인 방사선계측기의 성능평가 결과를 분석하여 봄으로서 나타난 문제점 등을 토의하여 보았다.
