介绍了一次包括四种环境样品的 γ 谱法分析比对。该比对中的三种样品是由一些具有已知核素比活度的标准物质或准标准物质构成,而另一种是活度未知的盲样。文中详细叙述了一种用于确定比对盲样参考值的新方法——实时加权平均模式,并且与其它方法进行了比较。
A gamma-spectrophotometric analysis of four environmental samples is presented. Three of the samples in the alignment consisted of some standard or quasi-standard materials with known nuclide specific activity, and the other was a blind sample of unknown activity. In this paper, a new method for determining the reference of blind samples (real-time weighted average) is described in detail and compared with other methods.
