초록

신속한 유류오염 조사를 위해 자연 방사성 동위원소인 Rn-222를 추적자로 활용하였다. 디젤유로 오염된 화강암 토양시료중의 Rn-222를 액체섬광계수기를 사용하여 분석한 결과 라돈 농도는 유류의함량에 비례하여 감소하였으며 13%까지 오염시킨 경우 Rn-222의 함량은 30% 까지 감소하였다. TCE로오염된 지하수의 오염범위를 알기위해 Rn-222를 물과 유류간의 분배계수차이를 활용한 추적자로 사용하였다. 원주의TCE 오염 지하수에 대한 오염범위를 예측하기 위해 Rn-222 분석을 수행하였다.

Abstract

Rn-222 was used as a natural radioactive isotope tracer to evaluate non-aqueous phase liquid(NAPL)contaminated soil and aquifer. In the case of soil sample, Rn-222 concentration was inversely decreased with diesel concentration in the granite soil sample and it was decreased about 30% at the 13% diesel contaminated soil. For evaluating trichloroethylene (TCE) contaminated aquifer, the natural radioisotope Rn-222 was used as naturally occurring partitioning tracer for the approximate localization and semiquantitative assessment of the TCE source zone. Rn-222 was analyzed for the estimation of TCE contamination ranges of the acquifer in the contaminated site at Wonju in Korea.
