    초록

    본 연구에서는「공공수역 방사성물질 측정망 운영 계획」에 따른 모니터링 수행 내용을 소개하였고, 하천 및 호소 60개 지점을 대상으로 인공방사성물질(134Cs, 137Cs, 131I)의 농도를 조사하여 우리나라 지표수 내 방사성물질의 실태를 파악하고자 하였다. 채취된 시료는 마리넬리 비커를 이용한 감마분광분석기법으로 분석하였다. 134Cs와 137Cs은 모든 지점에서 MDA 미만으로 조사되었고, 131I는 한 지점(0.533±0.058 Bq/L)을 제외한 모든 지점의 농도가 MDA 미만으로 나타났다. 131I는 의료용으로 사용하는 물질로 환자의 배설물로 인해 하수처리장 인근 하천수에서 빈번하게 검출되는 물질로 알려져 있다. 따라서131I가 검출된 원인을 파악하기 위해 하수처리장 방류지점을 포함한 131I가 검출된 상류수계 6개 지점을 추가 조사하였다. 조사결과, 하수처리장 처리수 방류지점에서부터 하류방향으로 131I가 지속적으로 검출되었으며, 농도는 0.257±0.034~0.799±0.051 Bq/L 범위로 조사되었다. 추가조사를 통해 하수처리장 방류수가하천수의 131I 검출에 영향을 미치는 것으로 나타났다.

    Abstract

    A survey of the artificial radionuclides in rivers and lakes was conducted to investigate their levels in surface water. Water samples were collected at 60 points and analyzed by gamma-ray spectrometry with a measurement time of 10,000 seconds for 134Cs, 137Cs, and 131I. The obained values were lower than MDA for all points, except one point for 131I that was 0.533±0.058 Bq/L. 131I is known as a radioactive material that occurs frequently in sewage treatment plants. Because it is often used for medical treatments and subject to spreading into the environment due to the excretion from the patients. For the point where 131I was detected, we conducted additional investigation on the upstream river point and the effluent points of nearby sewage treatment plant to find the source of 131I. 131I was not detected at the upstream points of one of the upstream sewage treatment plants but found at the downstream points with the level being 0.257±0.034 to 0.799± 0.051 Bq/L, proving the sewage treatment plant was the 131Isource.
