초록
환경시료중의 삼중수소준위를 조사하기 위하여, 국내 12개 지역에서 채취한 생물시료(쌀, 채소, 솔잎)중의 삼중수소를 분석하였다. 생물시료중의 삼중수소는 동결건조법과 건조시료의 연소법에 의해 조직자유수 삼중수소 (TFWT: Tissue-Free Water Tritium)와 조직결합수 삼중수소 (TBT: Tissue-bound tritium)로 분류 추출하였으며, 액 체 섬광계수기(Liquid Scintillation Counter)를 이용하여 각 시료중의 삼중수소를 측정하였다. TFWT 농도는 쌀의 경우
To evaluate tritium level in some environmental samples, tissue-free water tritium (TFWT) and tissue-bound tritium (TBT) were analyzed in rices, chinese cabbages and pine needles collected at 12 locations in Korea. The TFWT was recovered by freeze-drying of the samples and the TBT was obtained in the form of water by combustion of the dried samples. Tritium was measured by liquid scintillation counter. The concentrations of TFWT were in the range of
