Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a radiation dose measuring method having high reproductivity and a glass for radiation detection.SOLUTION: A glass for radiation detection containing, by mol%, SiO+BO:0.1 to 30%, SiO:0 to 20%, BO:0 to 10%, PO:40 to 80%, AlO:1 to 30%, NaO:5 to 40%, AgO:0.01 to 2% is heat treated in a temperature range of (glass transition point/4) to (glass transition point/2.5) to stabilize fluorescence intensity and then fluorescence intensity is measured. There is provided a glass for radiation detection further containing MgO:0 to 10% and ZnO:0 to 10%, and PO/(SiO+BO+AlO) with 1.2 or more by molar ratio.SELECTED DRAWING: None 【課題】高い再現性を有する放射線量測定方法及び放射線検出用ガラスの提供。【解決手段】モル％で、ＳｉＯ２＋Ｂ２Ｏ３：０．１〜３０％、ＳｉＯ２：０〜２０％、Ｂ２Ｏ３：０〜１０％、Ｐ２Ｏ５：４０〜８０％、Ａｌ２Ｏ３：１〜３０％、Ｎａ２Ｏ：５〜４０％、Ａｇ２Ｏ：０．０１〜２％を含有する放射線検出用ガラスを、（ガラス転移点／４）〜（ガラス転移点／２．５）の温度範囲で熱処理して蛍光強度を安定化した後に蛍光強度を測定する。更に、ＭｇＯ：０〜１０％、ＺｎＯ：０〜１０％を含有し、モル比でＰ２Ｏ５／（ＳｉＯ２＋Ｂ２Ｏ３＋Ａｌ２Ｏ３）１．２以上を含有することが好ましい放射線検出用ガラス。【選択図】なし
