摘要:
质子治疗是目前肿瘤放射治疗先进的手段之一，但质子治疗设施在使用中会产生辐射，为了确保其安全运营，周围环境和人员所受到的电离辐射满足国家相关规范要求，需要考虑质子治疗设施的辐射防护问题。通过对质子治疗机理和屏蔽原理的分析，提出辐射防护设计方法，即确定辐射防护设计目标，进行源项评估，综合考虑设备使用的便利性和安全、工程造价等因素，确定屏蔽材料和参数，经屏蔽计算，设置安全联锁系统和辐射监测系统，确保医护人员受到的职业照射、大众受到的公众照射满足安全剂量要求。 Abstract:Proton therapy is currently one of the advanced tumor radiation therapy, but using proton therapy facility will produce radiation. In order to ensure its safe operation, environment and personnel by ionizing radiation meet the relevant national standards requirements, the proton therapy facility of radiation protection need to be considered. In this article, analysis of mechanism of proton therapy and shielding principle, the article puts forward the design method of radiation protection, which determine the radiation protection design goals, assess the source term, considering the convenience and safety of equipment use, engineering cost and other factors, shielding materials and parameters, the shielding calculation, set the safety interlock system and radiation monitoring system, and ensure that medical staff occupational exposure, satisfies the requirement of safety dose by public exposure of the masses. -
