| 摘 要： | 文中介绍了如何使用无氚水作为猝灭剂制备系列猝灭源,建立猝灭校正曲线,从而精确标定Quantulus1220液闪仪测量3H的计数效率。实验结果表明,直线拟合校正曲线计算的效率与测量值的偏差小,计数效率变动范围在21.59%～22.68%之间,系列猝灭源刻度仪器计数效率具有快速可靠等优点

| Abstract: | This paper introduces a simple and practical way to construct quenching calibration curve for tritium DPM measurements basing on efficiencies of a series of known activity standard sources and quenching parameter SQP(E)used to define the quench level in Quantulus 1220.Ten standard sources and two test samples were prepared with tritium-free water as quenching materials and progressively added to Hisafe 3 cocktail.A linear curve or polynomial function curve was fitted with each pair of quench parameter SQP(E)and efficiency of standard source.The test sample demonstrated that the error of linear curve was small within routine quenching range of 776 to 785.Therefore,the quenching calibration curve can be beneficial to improving accuracy and reliability of tritium counting. |
