纯
β
核素液闪测量技术应用广泛,实际工作中往往需要确定核素的测量效率;但除
3
H、
14
C等半衰期较长的核素外,多无系列猝灭标准源,给工作带来很多不便。本文根据国外有关方面研究,做了以
3
H标准源为基准、通过理论计算求出其它纯
β
核素在均相条件下的测量效率和猝灭校正曲线,进而求得放射性的活度。本方法使用简便、结果可靠、实用性强。
In this paper
we present a method to determine the relationship of liquid-scintillation counting efficiency between
3
H and any of the 34 pure beta-particle emitters based on the figure of merit. The calculated quench curve for any interested radionuclide can be obtained from the experimental quench curve for
3
H and the corresponding efficiency relationship table.
