Luminescence dosimetry was performed using bricks from the former settlement of Metlino, Southern Urals, Russia, to investigate the feasibility of validating the Techa River Dosimetry System (TRDS) 2016 for the shore of the Metlinsky Pond, upper Techa River region. TRDS is a code for estimating external and internal doses for members of the Extended Techa River Cohort. Several brick samples were taken from the north-western wall of the granary, facing the Metlinsky Pond. Samples were measured at different heights and at different depths into the bricks. Dating of the granary was performed by analyzing well shielded bricks. Assessment of the gamma dose-rate at the sample positions was done by thermoluminescent dosimeters and the dose-rate in front of the granary mapped with a dose-rate meter. Anthropogenic doses in bricks vary from 0.8 to 1.7 Gy and show an increase with sampling height. A similar height profile is observed for the current gamma dose-rate, which is compatible with the results of the dose-rate mapping. Implications for validating the TRDS are discussed.
使用俄罗斯南乌拉尔梅特林诺前定居点的砖进行了发光剂量测定，以研究验证特恰河剂量测定系统（TRDS）2016 用于上特恰河地区梅特林斯基池塘岸边的可行性。TRDS 是一种用于估算扩展特恰河队列成员的外部和内部剂量的代码。从面向梅特林斯基池塘的谷仓西北墙采集了几个砖样。在砖内的不同高度和深度处测量了样品。通过分析有良好屏蔽的砖对谷仓进行了定年。使用热释光剂量计评估了样品位置的伽马剂量率，并使用剂量率计在前述谷仓前绘制了剂量率图。砖中的人为剂量从 0.8 到 1.7Gy 不等，且随采样高度增加而增加。当前伽马剂量率也呈现出类似的高度分布，这与剂量率测绘的结果一致。文中讨论了验证 TRDS 的影响。
