NDA测量铀的工作标准样品用于仪器刻度、测量方法研究和物料的定量分析,同时也可用于NDA仪器的日常监测与方法研究的质量控制,本工作研制了一套低富集度铀工作标准样品和一套低富集度铀质量工作标准样品,装料样品共计23件,空容器3件。铀工作标准样品的特征量具有适当覆盖范围和分布梯度,U3O8质量和235U富集度的相对偏差
NDA Uranium working standard samples for instrument calibration, measurement methods and materials quantitative analysis, but also can be used for routine monitoring of NDA instruments and methodological research quality control, this work developed a set of low enrichment uranium working standards Samples and a set of low enriched uranium quality standards, loading a total of 23 samples, 3 empty containers. The characteristic quantities of the uranium working standard samples have appropriate coverage and distribution gradients, relative deviations of U3O8 mass and 235U enrichment
