Research on radiation induced luminescence for dosimetric system applicable in high-dose-rate radiation environments

为了将光学传感器应用于大范围的辐射剂量率剂量测定（低剂量率伽马射线场、高剂量离子、低剂量率快中子等），研究了候选陶瓷的辐射发光行为，并进行了适用剂量测定系统的材料选择。提出了一种采用耐辐射硅芯光纤的光学剂量测量系统，该系统具有宽动态范围，可应用于福岛核电站环境辐射监测等复杂辐射环境。

For application of optical sensors for a wide range of radiation-dose-rate dosimetry (low dose rate gamma-ray field, high dose rat ions, low dose rate fast neutron, etc.), radioluminescent behaviors of candidate ceramics were examined and materials selection for applicable dosimetric systems were carried out. With radiation resistant silica-core optical fibers, the optical dosimetric system was proposed which had a wide dynamic range and could be applied to a complicated radiation environment such as an environmental radiation monitoring at the Fukushima site.
