摘　　要：利用非破坏性分析法检验用于刻度分段γ扫描(SGS)装置的标样。采用分段γ扫描技术测量了8个装有U3O8的铀标样、8个装有PuO2的钚标样。检测铀标样和钚标样装钚量的准确性以及铀标样中U3O8和钚标样中PuO2与介质混合的均匀性。检测结果表明:SGS标样的装料量的准确性好于1%,标样中料样和介质混合的均匀性好于3%。The quality of a series of uranium calibration standards and a series of plutonium calibration standards for the segmented gamma scanning（SGS） was verified. It is important to analyze the proper quality of the special nuclear material in the standards and its homogeneity in the matrix was measured by gamma ray non-destructive assay （NDA）. As a result, the measured values of each series standards are agreeable with declared within 1 %. And the measured results of the material uniformity in matrix for both series of the standards are better than 3%.
