摘要: A scintillator is disclosed that comprises a ceramic of rare-earth oxysulfide activated with Pr, such as Gd 2 O S:Pr, having: (1) ratio peak value at about 270 K to 140 in glow curve 0.01 or less, when the thermoluminescence intensity measured rate temperature increase 15±5 K/min after 20 minutes irradiation ultraviolet rays having wavelength 254 nm and power 1 W/m liquid nitrogen temperature, (2) 630 512 410 resolution less.
