摘要
Abstract
An effective method is found that ~(90)Sr and ~(90)Y can be measured by measuring the bremsstrahlung produced in a ~(90)Sr and ~(90)Y sample. According to the metrical principle, the detection efficiency ratio k of ~(90)Y to ~(90)Sr is obtained by measuring a ~(90)Sr sample from which ~(90)Y has been removed by extraction of ~(90)Y with di(2-ethylhexly) phosphoric acid (HDEHP). The results indicate that the simultaneous measurement of ~(90)Sr and ~(90)Y is feasible and ~(90)Sr-~(90)Y can be directly used as the tracer of Y.
