本文对71例尸检病人的肝、脾和骨髓中的吸收剂量进行了估算。组织中的232Th含量由228Ac γ射线测量和228Ac与232Th的活度比确定。在计算吸收剂量时，Kaul的数据被用作232 Th与其子体之间的稳态活度比和Thorotrast聚集体中α射线的自吸收值。估计累积剂量的尸检病例包括45例恶性肝肿瘤病例、12例肝硬化病例、7例血液病病例和7例其他疾病病例。给出了器官吸收剂量的估算值，并讨论了器官组织辐射效应与剂量的关系。
The absorbed dose in the liver, spleen and bone marrow of Thorotrast patients was estimated for 71 autopsy cases. 232Th amounts in tissues were determined from measurements of 228Ac gamma-rays and the activity ratio of 228Ac to 232Th. In calculating the absorbed dose, Kaul's data were used as values of the steady state activity ratio between 232Th and its daughters and the self-absorption of alpha-rays in Thorotrast aggregates. The autopsy cases in which the cumulative dose was estimated consisted of 45 cases of malignant hepatic tumor, 12 cases of liver cirrhosis, 7 cases of blood disease and 7 cases of other diseases. The estimated absorbed doses in the organs were presented and the relationship between the dose and radiation effects on organ tissues was discussed.
