效率融洽法Yb-169活度测定

An application of harmonizing efficiency method in an intercomparison on measuring activity of Yb-169

本文详细介绍了在一次169Yb点源的活度测量比对中针对短寿命核素样品测量的特点而采取的数据处理方法。提出了效率融洽法的概念,介绍对待测源的效率与活度的乘积值ε(Eγi)×A采用效率融洽法改善测量系统在关心能区的效率刻度准确性的尝试,并取得了比较满意的比对结果。

In this paper, the methods used for processing activity data of radionuclides of short life are presented. A concept of harmonizing efficiency method was employed to improve veracity of efficiency scale in energy range of interest, using the products between efficiencies and activity, i. e. ε（Eγi）×A, of the source being measured, and more satisfying intercomparison result was obtained.
