The possibility of using a single grain OSL attachment system developed by the Risø National Laboratory (Roskilde, Denmark) for assessing the spatial distribution of radionuclides incorporated in human tissues was investigated. Detectors containing arrays of single grains of alpha-Al2O3)C powder (Landauer Inc., USA) were prepared using aluminium discs (diameter 9.7 mm), which can accommodate 100 single grains in 0.3 mm holes positioned in a 10 x 10 grid. The luminescence and dosimetric properties of each grain were investigated by exposing the detectors to uniform photon radiation fields. After the characterisation of the detectors, the systems were tested to assess the spatial dose rate distribution because of 90Sr incorporated in a tooth sample extracted from an inhabitant of the Techa River region.
研究了使用丹麦罗斯基勒的里瑟国家实验室开发的单颗粒光释光（OSL）附着系统来评估人体组织中所含放射性核素空间分布的可能性。使用铝盘（直径9.7毫米）制备了包含α-Al2O3:C粉末单颗粒阵列的探测器（美国Landauer公司），该铝盘在10×10网格中0.3毫米的孔中可容纳100个单颗粒。通过将探测器暴露于均匀光子辐射场来研究每个颗粒的发光和剂量学特性。在对探测器进行表征后，对该系统进行了测试，以评估因取自捷恰河地区一名居民的牙齿样本中所含90Sr而产生的空间剂量率分布。
