| 摘 要： | 描述了＾８９Ｓｒ样品中含量为１０＾－６级的＾９０Ｓｒ测定方法，采用层析法先使钇与部分锶分离。再通过对原点纸段半衰期的测定确定＾９０Ｙ和＾９０Ｓｒ的准确含量，从而确定出＾８９Ｓｒ样品中＾９０Ｓｒ的含量，该方法简便，易行，有效地达到了实际使用的目的。

| Abstract: | A procedure used to determine 90Sr content in 89Sr product was developed.According to the decay principle, 90Sr maintains long term equilibrium with daughtercoy. So, 90Sr content can be determined through 90Y determination. Paperchromatography was used to separate yttrium from stronium, accurate determinationsof 89Sr content and 90Y content were obtained on the basis of half-life measuringmethod. At last, 90Sr content was determined. The procedure is effective, simple andconvenient. |
