| Research Abstract |
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.
