90년대 후반부터 최근까지 우리나라 심성암류 중에서 우라늄(U)과 라돈(Rn)이 집중된다고 보고되고 있는 암류는 무엇인가? | 일반적으로, 우리나라는 오랜 지질시대동안 항상 판의 경계와 가까운 부근에 위치하여 다양한 암석들(화성암, 변성암 및 퇴적암)이 형성되거나 소멸되기 쉬운 환경을 만들었고, 특히 화성활동이 활발하였다. 국내에서 화성활동에 의해 생성된 심성암 계열은 국토면적의 약 40%이상을 차지하며, 1990년대 후반부터 최근까지 심성암류 중 중생대 화강암류에 고함량 우라늄(U)과 라돈(Rn)이 집중된다고 보고하고 있다(NIER, 2010; Hwang, 2018 and references therein). 특히, 대전지역에 분포하는 쥐라기 전기의 후기(186-184 Ma; Jo et al. | |
국내에서 화성활동에 의해 생성된 심성암 계열이 국토면적에서 차지하는 비중은? | 일반적으로, 우리나라는 오랜 지질시대동안 항상 판의 경계와 가까운 부근에 위치하여 다양한 암석들(화성암, 변성암 및 퇴적암)이 형성되거나 소멸되기 쉬운 환경을 만들었고, 특히 화성활동이 활발하였다. 국내에서 화성활동에 의해 생성된 심성암 계열은 국토면적의 약 40%이상을 차지하며, 1990년대 후반부터 최근까지 심성암류 중 중생대 화강암류에 고함량 우라늄(U)과 라돈(Rn)이 집중된다고 보고하고 있다(NIER, 2010; Hwang, 2018 and references therein). 특히, 대전지역에 분포하는 쥐라기 전기의 후기(186-184 Ma; Jo et al. | |
2019년 11월에 마련된 건축자재 라돈 저감·관리 지침의 핵심내용은 무슨 내용인가? | 최근, 국내 석재산업의 영향을 줄 수 있는 건축자재 라돈 저감·관리 지침을 정부 관계부처 공동(환경부, 국토교통부, 원자력 안전위원회)으로 2019년 11월에 마련했다. 이 지침서의 핵심은 ‘방사능 농도지수’에 따른 기준치를 도입해 건축자재의 라돈 오염을 관리한다는 내용이다. 적용대상은 공동주택에 건축 내장재로 사용되는 천연석 기반의 자재이며, 이 기준 은 2020년 6월부터 적용하고 있다. |
