摘要
利用散射线作“内标”,对黄金首饰进行黄金含量K值的无损定量分析。用放射性同位素^(241)Am环状源激发样品,源强18.5GBq,测量最佳准确度为0.29％。
Scattered source lines can be used as an internal standard for determing the K value in gold ornements. The samples were excited by an annular 241Am source with an activity of 18. 5 GBq. The best measuring accuracy was 0. 29%.
