摘要

利用数值模拟的方法对各种不同模型进行了大量计算

研究了在一般几何条件下

核材料自吸收修正曲线的规律。结果证明核材料自吸收修正曲线与源区几何形状及大小无关。这一结论对许多实际问题很有意义并为进一步分析测量数据提供了依据。最后

应用这一自吸收修正形式进行了简单的核素分析。

Abstract

The regularities followed by γ-ray self-absorption corrections of nuclear materials under common geometry conditions have been studied by the numeric simulation. Many models were adopted. The results show that the self-absorption corrections are not related to shape and size of the sources. The method is succinct

and the conclusions are useful for actual situation and offer bases for data analyzing. The component of a sample is analyzed by means of the self-absorption correction.
