A variety of micro-scale structures based on radiophotoluminescent (RPL) centres in Ag-activated glasses and in LiF crystals were visualised by confocal microscopes. The origins of different RPL intensity profiles in a plateau region along the axial direction in both materials were examined and discussed. Moreover, we also reported the demonstration of a variable periodic time operated fibre-coupled dosimetry system using Ag-activated glass. In order to overcome the inevitable “build-up”effect occurring in RPL glasses during and after X-ray irradiation, pertinent experiments were carried out. Build-up curves and corresponding build-up rates were measured for different excitation wavelengths,temperatures and variable intervals were examined. The quick response of the dosimetry system developed here to the on/off switching operations was confirmed., 研究課題/領域番号:17H03519, 研究期間(年度):2017-04-01 – 2020-03-31, 出典:「光子,重粒子を照射した銀活性ガラス線量計の蛍光核飛跡の可視化と高性能化」研究成果報告書 課題番号17H03519 (KAKEN:科学研究費助成事業データベース(国立情報学研究所)) (https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-17H03519/17H03519seika/)を加工して作成, 金沢大学人間社会研究域学校教育系}, title = {光子,重粒子を照射した銀活性ガラス線量計の蛍光核飛跡の可視化と高性能化}, year = {2020} }
