摘要
采用碳还原法合成了SrS∶Eu,Sm,并对光激励发光材料SrS∶Eu,Sm的辐射剂量特性进行了研究。将SrS∶Eu,Sm材料做成PMMA剂量片在60Coγ源下接受辐照,然后用自己搭建的在线实时测试系统对剂量片发出的荧光信号进行测量。主要探讨了光激励发光材料SrS∶Eu,Sm在辐射剂量测量中的应用。
The SrS：Eu, Sm was prepared by carbon reduction method, and the radiation characteristics of optically stimulated luminescence material SrS： Eu, Sm was described. The PMMA films of SrS： Eu, Sm was placed into the radiation source, then the fluores-cence signal which sent out from dosimeter films was measured with the test system build up by ourselves. The relation between the radiation dose and the fluo-rescence intensity of the dosimeter sheet was carried out. This article mainly discussed the application of optically stimulated luminescence material SrS： Eu, Sm in radiation dose measurement.
