| 摘 要： | 采用同位素稀释法由10Be标准参考物质SRM4325制备系列 10Be/9Be标准样品,在北京HI-13串列加速器的AMS系统上对该系列标准（n(10Be)/n(9Be)范围为2.68×10-11~2.38×10-12）进行测量。测量结果显示，n(10Be)/n(9Be)测量值与标称值呈良好线性关系，且归一化后的测量值与标称值吻合。该系列标准可用于北京HI-13串列加速器的AMS系统对地质环境样品中10Be/9Be绝对比值的准确测定。

| Abstract: | By dilution of 10Be reference material(SRM 4235) with natural beryllium, the 10Be/9Be standard samples were prepared to be used as AMS standard. 4 10Be/9Be samples with n(10Be)/n(9Be) range from 2.68×10－11 to 2.38×10-12 were checked by AMS at the HI-13 tandem in CIAE. The measured results show the excellent linear relationship between measured values and respective nominal values for 10Be/9Be standard samples. Moreover, normalized measured values are in good agreement with their nominal values. The prepared 10Be/9Be standard samples can be used for accurate AMS measurements of environmental 10Be/9Be. |
