摘　　要：采用钴60-γ射线(装源75万居里)对珍珠蚌贝壳板材进行辐照加工8 h、12 h和16h,观察其颜色和光泽的变化,分别检测其吸收剂量。结果表明,经过钴60辐照加工,珍珠蚌贝壳板材颜色由银白色、粉红色转变为深灰色、灰黑色和蓝紫色等,光泽增强。珍珠蚌贝壳板材辐照剂量为9.3 KGy时,其颜色和光泽达到最佳状态,并呈现明显的彩虹效应。After processing pearl shell plate by irradiation technology with60Co-γ irradiation(0.75 million curies of radiation source) for 8 h,12 h and 16 h, observed its changes in color and luster, and determined its absorbed dose of irradiation. Results showed that the color of pearl shell plate changed from silver white, pink to dark gray, grayish black and purplish-blue, etc., and its luster increased. When the irradiation dose was 9.3 KGy, the color and luster was at its best, appearing obvious rainbow effect.
