医用直线加速器机房的防护改建

目的:对加速器机房进行改建,使改建后的机房放射防护效果符合国家标准要求。方法:根据最优化原则和国家放射防护有关文件要求,计算出补充屏蔽厚度的相关数据,并根据计算结果采用合理的方案对加速器机房进行防护改建。结果:改建工程设计合理,改建后加速器控制室和周围环境的各项放射防护指标均低于国家标准限值。结论:改建后加速器机房各项放射防护指标均达到国家标准要求,改建设计方案合理,且造价低,符合最优化原则。

Reconstruction of Medical Linear Accelerator Room

Objective To reconstruct the medical linear accelerator room to meet the requirements of the state standards. Methods Optimization principle and state standard for radiation protection were mobilized to calculate the shielding thickness, then the medical linear accelerator room was reconstructed accordingly. Results The radiation protection indexes of the reconstructed linear accelerator room and the surrounding environment were all less than the limit of the state standard. Conclusion The reconstructed linear accelerator room can satisfy the requirements of the state standard and optimization principle.
