Development of Passive Type Dosimeter Exhibits Adsorption Property by Using Ag-exchanged Zeolites

Abstract

After the accident in Fukushima Daiichi Nuclear Power Plant, evaluation of radioactive wastes in environment, such as Cs and Sr, is required extensively in Japan. Therefore, we aimed development of dosimeter exhibits adsorption property by using Ag-exchanged zeolites. In this study, we investigated emission property in Ag-exchanged FAU-Y and LTA zeolites before and after irradiation of ionizing radiation. In Ag-exchanged FAU-Y and LTA zeolites, the emission intensity increased with increase in absorption dose. This result indicates that Ag-exchanged FAU-Y and LTA zeolites are candidate for dosimeters.
