摘要: 辐射剂量中的内照射剂量无法直接测量,只能根据活度测量结果由生物动力学模型、剂量模型及相关参数计算获得。自从19世纪80年代以来,涉及内照射剂量计算领域的“剂量学计算模式与参数”、“生物动力学模型及参数”、“核衰变相关参数”等已发生变化,由此形成新的计算框架。自2015年的130号出版物开始,ICRP发布了一系列报告(目前还未完结),给出了“新计算框架”下的剂量系数,及根据活度测量结果可直接求得待积剂量的Z(t)函数等有关生物样品测量解释的最新结果,用于替代ICRP 30、68、54以及78号出版物。本文选取了32种常见核素,对原有数据与ICRP新的计算结果进行了比较。可以看出,新出版物给出的各种核素的剂量系数基本都有所变化,同时对吸收类型的划分更为丰富。

Abstract: The internal dose, which couldn't be directly measured, can only be calculated from the biokinetics model, dose model and related parameters based on the activity measurement results. Since the 1880's, there have been lots of changes in the relevant fields of dose models, biokinetics models, and radiological decay related parameters, thus forming a new calculation framework. Since its No.130 published in 2015, ICRP has released a series of reports to replace ICRP No.30, No.68, No.54 and No.78 (not yet finished), giving the dose coefficient under this framework and the latest results on the interpretation of biological sample measurements, such as the Z(t) function, which can be directly used to calculate effective dose based on the activity measurement results. We select 32 common nuclide to compare the old data with the new calculation results of ICRP. It can be seen that the dose coefficients of various nuclides given in the new publications have basically changed, and the absorption types are more diversified.
