The aim of the work was to develop new radioactive standard sources based on epoxy resins. The optimal proportions of the components and the homogeneity of the matrices were determined. The activity of multigamma sources prepared in Marinelli beakers was determined with reference to the National Standard of Radionuclides Activity in Poland. The difference of radionuclides activity values determined using calibrated gamma spectrometer and the activity of standard solutions used are in most cases significantly lower than measurement uncertainty limits. Sources production method and quality control procedure have been developed.
这项工作的目的是开发基于环氧树脂的新型放射性标准源。确定了各组分的最佳比例以及基体的均匀性。在马林内利烧杯中制备的多伽马源的活度是参照波兰放射性核素活度国家标准测定的。使用校准伽马能谱仪测定的放射性核素活度值与所用标准溶液活度之间的差异在大多数情况下明显低于测量不确定度限值。已制定了源的生产方法和质量控制程序。
