摘要

在实验室仅存在混合刻度源条件下，探讨不同解谱方法对放射性核素活度估算的适用性。本文利用HPGe γ谱仪测量样品，并分别采用效率曲线法和相对比较法来分析样品中

K核素活度。结果表明，若干扰核素对样品中待分析核素产生的影响可忽略，但对混合刻度源中相应的待分析核素影响较大时，经综合考虑，相对比较法所得结果优于效率曲线法；若干扰核素对样品中待分析核素产生的影响不可忽略，但对混合刻度源中相应的待分析核素影响不大时，与相对比较法相比，效率曲线法占优势。

Abstract

Background:

Currently

mixture calibration sources

generally used in laboratory for saving cost

are limited in spectrum analysis.

Purpose:

The aim is to study the suitability of two spectrum analysis methods under the condition of mixture calibration source.

Methods:

In this work

four radionuclides

241

137

and

were measured by HPGe γ spectrometry and analyzed with relative comparison and efficiency curve methods under the condition of the mixture calibration source.

Results:

Relative comparison method can not calculate the radioactive activity of test nuclide influenced by interference nuclide

if interference nuclide could be ignored in mixture calibration source.

Conclusion:

Relative comparison method has an advantage comparing with efficiency curve method

if interference nuclide has no effect on test nuclide included in sample

but has a great effect on test nuclide included in mixture calibration source. However

efficiency curve method has an advantage comparing with relative comparison method. If interference nuclide has a great effect on test nuclide included in sample

but no effect appears on test nuclide included in mixture calibration source.
