α-活度ZnS(Ag)内闪探测法的应用检验

APPLICATION AND CHECKING OF α-ACTIVITY BY INNER SCINTILLATION METHOD OF ZnS(Ag)

本文介绍了用于测量铀、钍、镭、钋和一些人工核素的α—活度ZnS（Ag）内闪法，并将所得数据与其它实验室和其它方法的数据作了比较。实践证明：内闪法不仅探测效率高，分析周期短，费用低，并且精密度和准确度都较好。

This paper describes α-activity by inner scintillation method of ZnS(Ag) which can be used for determination of U, Th, Ra,Po and certain artificial nuclides. The obtained results are compared with data determined by other analytical methods and other laboratories. It is demonstrated in practice that inner scintillation method has not only high detection efficiency,short analytical period and low expense,but also satisfactory precision and accuracy.
