In the decommissioning of a nuclear power plant, especially for the decontamination of radioactive substances caused by the 2011 Fukushima nuclear power plant accident, which has affected reconstruction after the earthquake, dose evaluation and validation of the decontamination effect are very important. To prepare a novel passive-type dosimeter system, which can be applied to radiation dose monitoring and visualization of the two-dimensional distribution of ionizing radiation in a contaminated area, we tried to develop bead- and sheet-type glass dosimeters utilizing the radiophotoluminescence (RPL) phenomenon in Ag+-doped phosphate glass. It is confirmed that the bead-type glass dosimeter with a diameter of about 50 µm exhibits an intense RPL. It is found that the sheet-type glass dosimeter, which is made of bead-type glasses, is useful for the monitoring of radiation dose in a wide dose range and the visualization of dose distribution.
