摘要
采用直接掺杂法分别制备了硫酸渣—混凝土、硫酸渣—粉煤灰—混凝土和铅—混凝土屏蔽材料,用Na I(TI)探测器、多道脉冲幅度分析仪和WINXCOM软件分析它们对γ射线的辐射防护能力.结果表明:硫酸渣制备的屏蔽材料辐射防护性能优于已有的石灰岩制备的屏蔽材料和FPPB屏蔽材料,可用作射线屏蔽材料,并有望实现固体废弃物的合理利用.
Pyrite cinder-concrete,pyrite cinder-fly ash-concrete and lead-concrete shielding materials have been prepared by means of direct doping. Na I（ TI） detectors,multi-channel pulse amplitude analyzer and Win XCOM software were used to test and analyze their radiation shielding property. The results show that the radiation shielding property of shielding material containing pyrite cinder is better than the existing shielding materials prepared from limestone and FPPB. Consequently,it can be used effectively as shielding materials against gamma radiation,and is expected to achieve the goal of rational utilization of solid waste.
