描述了89Sr样品中含量为10-6级的90Sr测定方法。采用纸层析法先使钇与大部分锶分离，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80Sr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。
Describes the 89Sr sample content of 10-6 90Sr determination. Yttrium was first separated from most strontium by paper chromatography. The 90S and 90Sr contents were determined by measuring the half-life of the paper at the origin. The 90Sr content in 80Sr samples was determined. The method is simple, easy and effective to achieve the purpose of actual use.
