A method for determining activity of Sr and Sr in a sample where Sr and Y are not in equilibrium is presented. The method consists of an experimental design and equations for accurately calculating activity of Sr and Sr based on Y particle counts and the total counts of particles emitted from Sr, Sr, and Y in a sample. The equations are derived based on chemical separation sequences, particle counting sequences, and the Bateman equation. The presented method allows simultaneously obtaining the activity of Sr and Sr in a non-equilibrated Sr/Y system without the need of Cerenkov counting.
本文提出了一种测定样品中锶-85和锶-87活度的方法，该样品中锶和钇处于非平衡状态。该方法包括一个实验设计和一些方程，用于根据钇粒子计数以及样品中锶-85、锶-87和钇发射的粒子总数准确计算锶-85和锶-87的活度。这些方程是基于化学分离序列、粒子计数序列和贝特曼方程推导出来的。所提出的方法能够在无需切伦科夫计数的情况下，同时获得非平衡锶/钇体系中锶-85和锶-87的活度。
