用~(230)Th同位素稀释-α能谱法测定氯化稀土中~(227)Th的含量,然后根据由~(227)Ac衰变生成~(227)Th的生长时间及半衰期,计算~(227)Ac含量的方法,定量分析了氯化稀土中~(227)Ac的含
The content of ~ (227) Th in rare earth chloride was measured by ~ (230) Th isotope dilution-α spectroscopy. Then the growth time and half-life of ~ (227) Th produced by ~ (227) Ac decay were calculated. 227) Ac content, the content of ~ (227) Ac in the rare earth chloride was quantitatively analyzed
