摘要：
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. (C) 2003 Elsevier Science B.V.
