摘　　要：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。An intercomparison of four environmental samples analyzed by γ spectrometry was organized. Three samples consisted of standard or quasi-standard substances with known specific activities of some nuclides while the radioactivity of the other sample was unknown. The authors presents a new method, the model real time weighted average, used for determining the reference values of intercomparison and comparison with other methods.
