Scintillation properties of GPSLa23.5%:Ce have been compared to LYSO:Ce. Light yield and energy resolution of GPSLa23.5%:Ce is superior to LYSO:Ce. Light loss coefficient of GPSLa23.5%:Ce is larger than that of LYSO:Ce. The α/γ ratio of GPSLa23.5%:Ce is larger than that of LYSO:Ce. Attenuation coefficient at 60 and 662 keV γ-rays has been determined.
