土壤中^(90)Sr和生物灰中^(137)Cs测量比对

Intercomparison of Measurements of ^(90)Sr in Soil and ^(137)Cs in Biological Ash

介绍了浙江省辐射环境监测站组织实施的2009年全国辐射环境监测系统土壤中90Sr和生物灰中137Cs测量比对情况及其结果分析。比对结果表明,90%的测量值为满意结果,5%的测量值为有问题结果,5%的测量值为离群值。通过此次比对,基本上了解了全国辐射环境监测系统土壤中90Sr和生物灰中137Cs测量水平,为今后进一步开展系统内的质保工作提供了依据。

The results for ^90Sr in soil and ^137Cs in biological ash samples in the 2009 Countrywide Radiation Environmental Monitoring Network Measurement Intercomparison Program held by the Radiation Environmental Monitoring Station of Zhejiang Province were studied.The results of this intercomparison showed that 90% measurements results were satisfactory,5% were dubitable,and 5% were unsatisfactory.Through the intercomparison,the network measurement levels of ^90Sr in soil and ^137Cs in biological ash samples is basically ascertained,which provided the basis for the future quality assurance in the network.
