A general approach to increasing the radiation hardness of complex structure oxide scintillation crystals

An approach to increasing the radiation hardness of scintillation materials based on complex structure oxide single crystals is proposed. It is shown that damage of the scintillation mechanism and radiation-induced optical absorption are strongly suppressed when a crystal is doped by a specific impurity. The necessary impurity properties are formulated. The proposed approach is illustrated by radiation hardness improvement of the lead tungstate PbWO4 and yttrium perovskite YAlO3:Ce scintillation materials.
