Waterborne releases to the Techa River from the Mayak plutonium facility in Russia during 1949-1956 resulted in significant doses to persons living downstream. The dosimetry system Techa River Dosimetry System-2016D has been developed, which provides individual doses of external and internal exposure for the members of the Techa River cohort and other persons who were exposed to releases of radioactive material to the Southern Urals. The results of computation of individual doses absorbed in red bone marrow and extraskeletal tissues for the Techa River cohort members (29,647 persons) are presented, which are based on residence histories on the contaminated Techa River and the East Urals Radioactive Trace, which was formed in 1957 as a result of the Kyshtym Accident. Available Sr body-burden measurements and available information on individual household locations have been used for refinement of individual dose estimates. Techa River Dosimetry System-2016D-based dose estimates will be used for verification of risk of low-dose-rate effects of ionizing radiation in the Techa River cohort.
1949 年至 1956 年间，俄罗斯马雅克钚设施向捷恰河排放的水污染物导致了居住在下游的人们受到了大量辐射。开发了捷恰河剂量测定系统-2016D，该系统为捷恰河队列成员和其他暴露于放射性物质排放到南乌拉尔的人员提供了外部和内部暴露的个人剂量。本文介绍了捷恰河队列成员（29647 人）红骨髓和骨骼外组织吸收的个人剂量的计算结果，这些结果基于他们在受污染的捷恰河和 1957 年因克什特姆事故形成的东乌拉尔放射性痕迹上的居住史。已利用 Sr 体内负荷测量和个人家庭位置的可用信息来改进个人剂量估算。捷恰河剂量测定系统-2016D 基于剂量估算将用于验证捷恰河队列中低剂量率电离辐射效应的风险。
