人发样品由于取样简单方便,易于保存,在地方病因研究和作为环境污染监测的指示器方面,已引起人们的兴趣。 我们利用短照射10分钟、冷却3小时后直接测定样品γ谱的方法,分析了人发样品中Sr、Zn、Cu、Br、As、Sb,Mn、K、Na等九个元素。本文讨论了分析的准确度和精密度。 1.实验方法 Human samples are of interest because they are simple and convenient to sample and are easy to store. They are of great interest in endemic research and as an indicator of environmental pollution monitoring. The method of direct determination of γ spectrum of the sample after cooling for 3 hours by short irradiation of 10 minutes was used to analyze nine elements of human hair samples such as Sr, Zn, Cu, Br, As, Sb, Mn, K and Na. This article discusses the accuracy and precision of the analysis. Experimental method
