韧致辐射法同时测量90Sr和90Y

Simultaneous Measurement of 90Sr and 90Y by Measuring Their Bremsstrahlung

  • 摘要: 本工作提出了用韧致辐射法同时测量样品中90Sr和90Y的设想。采用二(2-乙基已基)磷酸萃取制备无90Y的90Sr溶液,应用阱型NaI(Tl)探测器进行跟踪测量,得到90Sr与90Y探测效率比k。根据k值,跟踪测量未知样品,可以得到样品中90Sr和90Y的量。因此可以直接用90Sr -90Y作为Y的示踪剂。
    Abstract: An effective method is found that90Sr and 90Y can be measured by measuring the bremsstrahlung produced in a 90Sr and 90Y sample. According to the metrical principle, the detection efficiency ratio k of 90Y to 90Sr is obtained by measuring a 90Sr sample from which 90Y has been removed by extraction of 90Y with di(2-ethylhexly) phosphoric acid (HDEHP). The results indicate that the simultaneous measurement of 90Sr and 90Y is feasible and 90Sr-90Y can be directly used as the tracer of Y.
