摘要

Abstract

用4

πβ

符合吸收曲线效率外推法，测定短寿命的医用同位素

131

I、

198

Au绝对强度。测量结果分别对本底、死时间、分辨时间进行了修正，同时还考虑了短半衰期引起的修正。对

131

I和

198

Au的最大测量误差分别为0.57%和1.7%。本装置稍作改变后，还测量了具有电子俘获衰变的核素。

The absolute intensity of medical isotopes

131

I and

198

Au with a short half-life has been measured by the efficiency extrapolation method of 4

πβ-γ

coincidence absorption curve. The result of the measurement has been corrected for background

dead time

resolving time respectively. The correction for the short half-life has also been considered. The maximum error of the measurement are 0.57% and 1.7% for

131

I and

198

Au respectively. After a little change of the apparatus

we have measured the nuclide with electron capture decay.
