초록

원전 방사선작업종사자의 내부선량평가를 위해 일반적으로 사용되고 있는 bed type 전신계측에 몬테카를로 방법을 적용하여 작업자에 대한 외부오염 계측특성을 평가하였다. 한국인 체형을 반영하는 voxel 모의 피폭체를 이용하여 내부오염시 측정 특성을 평가하였다. 외부오염 판별을 위해 BOMAB 모의 피폭체를 이용하여 신체 각 부위별 오염시 나타나는 측정 특성을 평가하였다. 가슴 부위 오염시 누운 자세와 엎드린 자세로 구분하여 외부오염시 계측 특성을 확인하였다. 정량적인 분석을 통해 bed type 전신계측기를 이용한 외부오염 판별이 가능함을 확인하였다.

Monte Carlo method was applied to discriminate the external contamination on radiation workers in nuclear power plants for internal dose assessment generally used with a bed type scanning detector whole body counter. Korean voxel model with internal contamination was used to estimate the detection patterns of whole body scanning. Also, the BOMAB model with various external contamination was assumed to compare with detection of radionuclides inside the human body. From the comparison of detection efficiency between front and back side up, external contamination was easily distinguished.
