Abstract Radiation doses accumulated in ceramic or brick and assessed by thermoluminescence (TL) or optically stimulated luminescence (OSL) measurements are commonly used as a source of independent dosimetric information, helpful for validation of retrospective estimates of population exposures to anthropogenic radiation sources. This work systematically evaluates contributions to the cumulative dose in brick samples located at different heights in a wall from anthropogenic and natural radiation sources and provides data for quantification of the natural background component of the total dose in the brick derived in TL/OSL-measurements. Al- and Cu-cased thermoluminescence dosimeters (TLD) based on Al2O3:C are used to measure contemporary doses in brick walls as benchmarks and for validation of the dose reconstruction procedures. Correspondingly, doses in TLD and in brick in the same locations and under the same irradiation conditions are obtained by Monte Carlo simulations of radiation transport in realistic geometries. The data obtained in the simulations indicate that energy response of Al-cased dosimeters agrees better with the energy response of the brick than the response of Cu-cased TLD. The derived dosimetric data and relationships between doses in TLD and in brick are systematically derived for different locations in the wall and above the ground and are be used in other dose reconstruction studies with luminescence techniques.

由于人为和自然环境辐射源在砖块和 TL 剂量计中的吸收剂量

摘要 在陶瓷或砖块中累积并通过热释光 (TL) 或光受激发光 (OSL) 测量评估的辐射剂量通常用作独立剂量学信息的来源，有助于验证人群对人为辐射源的回顾性估计。这项工作系统地评估了人为和自然辐射源对位于墙内不同高度的砖块样品的累积剂量的贡献，并提供了量化 TL/OSL 测量得出的砖块中总剂量的自然背景分量的数据。基于 Al2O3:C 的铝壳和铜壳热释光剂量计 (TLD) 用于测量砖墙中的当代剂量作为基准，并用于验证剂量重建程序。相应地，在相同位置和相同辐照条件下，TLD 和砖中的剂量是通过对现实几何中的辐射传输进行蒙特卡罗模拟来获得的。模拟中获得的数据表明，铝外壳剂量计的能量响应与砖的能量响应比铜外壳 TLD 的响应更符合。导出的剂量学数据以及 TLD 和砖中剂量之间的关系是针对墙壁和地面上的不同位置系统地推导出来的，并用于其他使用发光技术的剂量重建研究。模拟中获得的数据表明，铝外壳剂量计的能量响应与砖的能量响应比铜外壳 TLD 的响应更符合。导出的剂量学数据以及 TLD 和砖中剂量之间的关系是针对墙壁和地面上的不同位置系统地推导出来的，并用于其他使用发光技术的剂量重建研究。模拟中获得的数据表明，铝外壳剂量计的能量响应与砖的能量响应比铜外壳 TLD 的响应更符合。导出的剂量学数据以及 TLD 和砖中剂量之间的关系是针对墙壁和地面上的不同位置系统地推导出来的，并用于其他使用发光技术的剂量重建研究。
