| 摘 要： | 本工作提出了用韧致辐射法同时测量样品中~(90)Sr和~(90)Y的设想.采用二(2-乙基已基)磷酸萃取制备无~(90)Y的~(90)Sr溶液,应用阱型NaI(Tl)探测器进行跟踪测量,得到~(90)Sr与~(90)Y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~(90)Sr和~(90)Y的量.因此可以直接用~(90)Sr-~(90)Y作为Y的示踪剂.

| 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. |
