Outline of Final Research Achievements

In this study, we have tried to develop a novel dosimeter system which can discriminate the radiation types. The following results are obtained; ① It was confirmed that the radiation types can be discriminated utilizing the RPL spectrum analysis. ② Bead- and sheet-type glass dosimeters were prepared as well as a two-dimensional RPL image reading system which is effective to monitor two dimensional radiation dose distribution. ③ It was found that it is possible to discriminate the energy of radiations utilizing laminated sheet-type glass dosimeter.
