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.
对71例钍造影剂患者的尸检病例估计了肝脏、脾脏和骨髓中的吸收剂量。通过测量228Acγ射线以及228Ac与232Th的活度比来确定组织中的232Th含量。在计算吸收剂量时，使用考尔的数据作为232Th与其子体之间的稳态活度比以及钍造影剂聚集体中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、12例肝硬化、7例血液病和7例其他疾病。给出了各器官的估计吸收剂量，并讨论了剂量与器官组织辐射效应之间的关系。
