医用直线加速器辐射环境影响评价

Environmental Impact Assessment of Medical Linear Accelerator Radiation

本文介绍医用直线加速器运行产生的辐射环境影响评价方法。已知直线加速器各屏蔽墙及防护门的结构材料和厚度,通过计算周边人员所受的年有效剂量,从而评价医用直线加速器运行产生的辐射环境影响是否在国家标准允许的范围内。

This article describes the environmental impact assessment methods of the radiation generated by the runing. medical linear accelerator. The material and thickness of shielding wall and protective doors of the linear accelerator were already knew, therefore we can evaluate the radiation by the runing, medical linear accelerator whether or not in the normal range of national standard by calculating the annual effective radiation dose of the surrounding personnel suffered.
