摘　　要：报道对钨酸铅晶体作低剂量辐照损伤研究的实验装置、方法、和结果．利用北京计量科学研究院的小型６０Ｃｏ放射源对４块钨酸铅晶体作了辐照损伤的实验，发现光产额随辐照剂量的增加呈现指数衰减，最后趋于饱和．This paper presents a study on radiation damage of lead tungstate crystals(PbWO4),including experimental setup, experimental method and results. Four PbWO4crystals were irradiated and the light yield of PWO crystal before irradiated and afterinlaied were measured. The changes of light yield of PbWO4 with an exponentialattenuation was found.

关 键 词：钨酸铅晶体 光产额 辐照损伤 电磁量能器
