摘要

纯

发射体衰变率绝对测量的效率示踪法

［1］

是利用一种衰变率精确已知的适当的

β（

或

）核素作为示踪剂，并与待测核素在同样的条件下计数，然后把待测样品的计数率

当作示踪剂计数效率

的函数，外推到

βT

为1处。这样得到的外推值就被认为是待测样品的衰变率，用一个式子来表示，就是：

Abstract

The correspondance of the channel ratios was checked to evaluate the correspondance of the experimental spectra of two nuclides in a simplified efficiency tracing measurement of disinteg rating rate of tritium using

C as a tracer. A linear efficiency tracing curve was successfully obtained with an interpolation method of the channel ratio

in which the efficiency loss ratio is about 1.000±0.001.
