Abstract

The organically bound tritium(OBT) concentrations of the marine organisms(seaweed and shellfish) around Wolsung nuclear power plants were measured. The OBT concentrations of seaweeds were in the range of $0.372{\sim}2.72$ Bq/kg-fresh. The OBT concentrations of shellfish were in the range of $0.239{\sim}2.02$ Bq/kg-fresh. The internal dose due to the OBT concentration of seaweed was estimated as $3.4{\times}10^{-7}$ mSv/year.

월성 원자력발전소 주변의 해양생물(해조류와 패류) 시료를 채취하여 조직결합 삼중수소 (OBT) 방사능농도를 측정 분석하였다. 해조류의 OBT 방사능농도는 $0.372{\sim}2.72$ Bq/kg-fresh의 범위였으며, 패류의 OBT 방사능농도는 $0.239{\sim}2.02$ Bq/kg-fresh의 범위였다. 그리고 해조류의 OBT에 의한 내부피폭선량은 $3.4{\times}10^{-7}mSv/year$로 평가되었다.
