摘要
本文介绍了用放射化学和化学方法分析WHO-IRC提供的低水平环境放射性测量比对样品的主要程序和得到的结果。结果表明,^(90)Sr、^(137)Cs和Ca的分析结果达到了较高的准确度。文中对分析中影响准确度的几个问题进行了讨论。
A method for determining low-level radioactive nuclides in milk for intercomparison by WHO-IRC is presented in this paper. The results show that the values of 90Sr,137Cs, Ca concentration appear to he agreement with IRC reference values. Some problems concerning the effect on analytical accuracy have been discussed as well.
