【摘要】 介绍了全国辐射环境监测网络放射性气溶胶中γ核素测量考核情况及其结果分析。采用稳健统计方法处理测量结果表明,87.8%的测量值为满意结果,6.1%的测量值为有问题结果,6.1%的测量值为离群。通过比较测量结果的中位值与参考值,发现各核素测量值可能存在负的系统误差。利用此次考核,基本了解了全国辐射环境监测网络气溶胶中γ核素测量水平,为进一步做好网络质保工作提供了依据。更多还原

【Abstract】 The results for gamma nuclides in aerosol in State Environmental Radiation Monitoring Network Measurement Assessment Program in 2013,held by the Environmental Radiation Monitoring Station of Zhejiang Province,were presented. With robust statistical method employed,it showed that 87. 8% of measurement results were satisfied,6. 1% were dubitable,and remaining 6. 1% dissatisfied. Comparison of the resulted median and the reference values indicated there may be a negative system error for the measurements of every nuclide. With this program,the measurement capability of gamma nuclides in aerosol in the network was generally understood,which provided a basis for the future quality assurance in the respect.更多还原
