中文摘要 | 以液態閃爍計數法分析低濃度之環境氚水樣本,如古老地下水或深層海水時,受 到其計數效率低的影響,可偵測極很常常無法達到吾人之需求。為改善此一情形,可藉由環 境氚水樣本的電解濃縮,提昇對低濃度環境氚水樣本之分析能力,本文將介紹低濃度氚水溶液 之電解濃縮設備,以及實際氚水樣本之濃縮實驗操作與結果,根據本研究之初步實驗結果顯 示,目前已經能夠將低濃度氚水樣本之氚濃度提高至30倍以上,可偵測極限達到0.5TU。 |
英文摘要 | Due to low counting efficiency, the detectable limit of existing liquid scintillation counting (LSC) method usually cannot achieve the required level in the analysis of low concentration tritiated water such as old groundwater or deep sea water. In order to improve the analyzing accuracy for low concentration tritiated water, a tritium enrichment laboratory was established. This article describes the equipments in this laboratory, the enrichment procedures and several experimental results. At present, the enrichment factor achieved in this laboratory is around 30 and the detectable limit of LSC method can be lowered down to 0.5 TU. |
