| 中文摘要 | 目的为了评价LA45医用高能加速器测试场所是否符合辐射安全评价要求,估算了其对工作人员和公众年受照剂量,依据相关标准,进行评价。方法基于NCRP151号报告剂量估算模式计算了高能加速器测试产生的X射线、电子束、中子等不同种类射线产生的辐照剂量。结果结果表明该场所的辐射防护设施屏蔽和防护效果可以有效保障工作人员和公众的辐射安全。结论医用高能加速器在我国的使用尚属起步阶段,随着射线能量的提高,其存在的辐射风险也逐渐增大,本文提供的高能加速器辐射安全评价方法,为工作人员和公众的辐照安全提供了技术参考。; Objective To evaluate whether LA45 medical linear accelerator test site comfroms to the requirements of radiation safety evaluation,the radiation dosages of the workers and the public were calculated,and evaluated according to the relevant standards. Methods The dosages produced from different types of rays were calculated during high- energy medical linear accelerator's testing based on NCRP 151,such as X- ray,electron beam,neutron ray,etc. Results The results showed that the effects of the site's radiation protection facilities' shielding protection could protect effectively the radiation safety of the workers and the public. Conclusion The application of Medical high- energy medical linear accelerator was still in infancy in China,the radiation risk was gradually increased accompanied with the ray energy's increasing. The evaluation methods for high- energy medical linear accelerator's radiation safety,which were provided in paper,could provide technical reference for the optimization of radiation protection. |
