The thermoluminescence (TL) and optically stimulated luminescence (OSL) properties of high quality 0.8% Ce doped YAlO3 crystal (YAP:Ce) which is grown by Czochralski method are studied. It is found that YAP:Ce has high TL and OSL sensitivity comparing with that of high quality TL material LiFMg,Cu,P and OSL dosimetry material Al2O3C. The main glow peak of YAP:Ce locates at 701 K, which is 216 K higher than that of Al2O3C (485 K) and 194 K higher than LiFMg,Cu,P (507 K). The fact means that electrons in the traps of YAP:Ce are stable and are not influenced by the circumstance easily, and can be used in high temperature environment. So YAP:Ce crystal is a promising dosimetry material which can be used in special conditions.
