固体样品中总α放射性检出限与不确定度分析

Detection Limit and Uncertainty Analysis of Total α Radioactivity in Solid Samples

摘要: 通过对固体样品进行测量，分析固体样品总α法放射性的检出限与不确定度。测得固体样品总α放射性检出限在0.113～0.131 Bq/g，对应测量下限在0.452～0.524 Bq/g。总α放射性不确定度为19.80%(k=2)并对检出限与不确定度进行了探讨。

Abstract: In this paper, the detection limit and uncertainty of total α radioactivity in solid samples were analyzed by measuring solid samples. The detection limit of total α radioactivity in solid samples was 0.113～0.131 Bq/g, and the corresponding lower limit was 0.452～0.524 Bq/g. The uncertainty of total α radioactivity was 19.80%(k=2). The limit of detection and uncertainty were discussed in this paper.
