摘　　要：本文简要介绍一台3000kV、10mA电子加速器辐照站的屏蔽设计。设计中根据屏蔽计算和代价-利益分析方法确定防护墙厚度,其结果比制造厂推荐的厚度小得多。测量结果表明,工作环境的辐射水平稍高于天然本底。This paper outlines, the radiation protection design for a 3000kV, 10mA electron accelerator irradiation station. The design hasbeen accomplished in accordance with shielding calculation and theprinciple for optimization of radiation protection. The thickness of theshielding walls determined in this way was much smaller than thatrecommended by the accelerator manufacturer. Survey results showed thatthe radiation level in working area was only slightly higher than naturalbackground.
