【摘要】 采用碳还原法合成了CaS:Eu,Sm,并对光激励发光材料CaS:Eu,Sm的辐射剂量特性进行了研究。将CaS:Eu,Sm材料做成PMMA剂量片在⁶⁰Coγ源下接受辐照,然后搭建在线实时测试系统对剂量片发出的荧光信号进行测量。文中主要探讨了光激励发光材料CaS:Eu,Sm在辐射剂量测量中的应用。更多还原

【Abstract】 In this paper,CaS.Eu,Sm was prepared by carbon reduction method,the radiation characteris- tics of optically stimulated luminescence materialCaS:Eu,Sm is described.The PMMA films which made of CaS.Eu,Sm had placed into the radiation source,then the fluorescence signal which sends out from do- simeter films was measured with the test system which build up by ourselves.The relation between the radiation dose and the fluorescence intensity of the dosimeter sheet is carried.This article mainly dis- cussed the applied of Optically Stimulated Luminescence material CaS.Eu,Sm in radiation dose measure- ment.更多还原
