1958年10月15日南斯拉夫事故中所受辐射剂量的调查工作已经完成，调查采用了现代剂量测定技术。零功率反应堆在低功率水平下运行，以确定反应堆附近不同位置的伽马与中子剂量之比。这些测量是用特殊的计数方法进行的，其中一种方法是在伽马射线存在的情况下测量中子剂量，另一种方法是在中子存在的情况下测量伽马剂量。反应堆在较高功率水平下短时间运行，用阈探测器测定中子剂量，并在人造模型中研究了中子剂量与Na/sup 24/活化的关系。一个计算程序给出了同样三个量的理论结果。理论和实验结果吻合较好。给出了单个剂量的最终结果。在接受调查的7人中，最高剂量为436拉德，最低剂量为207拉德。先前估计的剂量以雷姆为单位报告，显示最高的中子剂量估计值为210雷姆，伽马剂量估计值为630雷姆，或总暴露量为840雷姆以上。（auth）«少
An investigation of the radiation doses received in the Yugoslav accident on 15 October, 1958, was completed, using modern techniques of dosimetry. The zero power reactor was operated at low power levels to determine the ratio of gamma to neutron dose at various locations near the reactor. These measurements were made with special counting methods, one of which measured the neutron dose in the presence of gamma rays, and the other measured the gamma dose in the presence of neutrons. The reactor was operated at a higher power level for a short time to determine the neutron dose by means of threshold detectors, and the relationship between neutron dose and Na/sup 24/ activation in manshaped phantoms. A computational program gave theoretical results for the same three quantities. The results of theory and experiment are in good agreement. Final results for the individual doses are given. Of the seven persons investigated, the highest dose received was 436 rads and the lowest dose was 207 rads. The doses previously estimated were reported in rem units, showing for the highest an estimated value of 210 rems for the neutron dose and 630 rems for the gamma dose, or a total exposure of 840more » rems.
