| 摘 要： | 本文报道了有9个实验室参加的芦苇和茶叶样品中锶-90和铯-137分析比对的结果。比对结果表明,各实验室芦苇中锶-90和茶叶中铯-137的分析结果可比性良好,遵从正态分布规律;少数实验室芦苇中铯-137的分析结果偏低;茶叶中锶-90的分析结果可比性差。本文讨论了分析结果差异的原因,估计了样品中锶-90和铯-137含量的95%置信区间。

| Abstract: | The results of intercomparison of methods for determining ~(90)Srand ~(137)Cs in plant samples are reported.Nine laboratories participatedin the intercomparison.The samples used in intercomparison were reed andtea powders.The analytical results of ~(90)Sr in reed and ~(137)Cs in tea fromdifferent laboratories show good comparability and follow the normal-distri-bution.Some results reported of ~(137)Cs in reed are apparently lower thanothers.The results of ~(90)Sr in tea from different laboratories have poor com-parability.The results obtained by HDEHP rapid extraction chromatographappear to be too high,and it's cause is discussed.The 95% confidenceintervals of content of ~(90)St and ~(137)Cs in reed and tea samples are given. |
