本文研究了在制备低本底KamLAND相时液体闪烁体中放射性的去除。本文介绍了测量和有效地提取液体闪烁体中氡衰变产物的方法和技术。我们报告的放射性同位素减少因子时，应用各种提取方法。在这项研究中，蒸馏被确定为最有效的方法，从液体闪烁体中去除氡生铅。
The removal of radioactivity from liquid scintillator has been studied in preparation of a low background phase of KamLAND. This paper describes the methods and techniques developed to measure and efficiently extract radon decay products from liquid scintillator. We report the radio-isotope reduction factors obtained when applying various extraction methods. During this study, distillation was identified as the most efficient method for removing radon-born lead from liquid scintillator.
