Abstract

Air kerma rate constant (Γδ) of a Cs137 source was evaluated in two different manners: (a) by calculation based on fluence-to-kerma conversion coefficient and (b) by measurements by different ionization chambers. Comparison between Γδ values of the Cs137 source, obtained from these two methods, shows the consistence within 0.5%. The combined standard uncertainties of these Γδ values (uΓδ) were also investigated, which were found as less than 2.0% and less than 6.0% for calculated and measured values, respectively. These Γδ values were also compared with those from published data.

[公式略]源空气克玛速率常数的测定

以两种不同的方式对Cs137源的空气克玛速率常数（Γδ）进行了评估：(a)通过基于影响-克玛转换系数的计算和(b)通过不同电离室的测量。两种方法得到的Cs137源的Γδ值比较，一致性在0.5%以内。研究了这些Γδ值（uΓδ）的联合标准不确定度，计算值和实测值的不确定度分别小于2.0%和6.0%。这些Γδ值也与已发表的数据进行了比较。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
