给出了一种用于推导近距离放射治疗中常用的核素的选择所产生的组织吸收剂量的技术。所需的各种参数已从蒙特卡罗计算机程序中获得，该程序从白色和Fitzgerald（1977 a）的方程中导出组织衰减数据。注意到并纠正了用于获得方程的数据中的一些不一致之处。有用的结果，特别是，可能与临床使用的125 I粒子的剂量测定误差突出。
A technique for deriving the tissue-absorbed dose resulting from the use of a selection of nuclides commonly employed in brachytherapy is given. The various parameters required have been obtained from a Monte Carlo computer program which derives tissue attenuation data from the equations of White and Fitzgerald (1977a). Some inconsistencies in the data used to obtain the equations are noted and corrected. Useful results are presented and, in particular, possible dosimetric errors associated with the clinical use of 125I seeds are highlighted.
