摘　　要：目的调查医疗机构相关从业人员对《放射治疗机房的辐射屏蔽规范第2部分:电子直线加速器放射治疗机房》(GBZ/T 201.2—2011)的了解情况以及该标准实施、应用情况并收集相关的问题和建议,评估标准的科学性、规范性和时效性,为该标准的进一步修订和实施提供科学依据。方法对全国22个省开展医用电子直线加速器放射治疗的医疗机构相关从业人员进行线上问卷调查,问卷内容主要包括GBZ/T 201.2—2011知晓情况、培训情况、应用情况和修订建议,收集问卷并分析调查结果。结果340名相关从业人员填写了问卷,66.80%的参与人员为物理师。79.11%的人员了解该标准,56.18%的人员参加过该标准培训,但调查结果显示从业人员对标准内容掌握程度不高,标准培训和宣贯力度不足;83.24%的人员认为该标准得到普遍应用,17.60%的人员认为该标准需要修订,76.76%的调查对象认为需要增加示例,88.82%认为对于10 MV X射线加速器机房要考虑中子屏蔽。结论该标准在放射治疗防护领域基本得到了普及,随着放疗技术的发展,标准应及时修订增加计算示例和考虑10 MV X射线加速器机房要考虑中子屏蔽。该标准有较强的技术性,不易掌握,可结合不同人群制定不同宣贯目标,加大重要岗位人员的培训力度,确保标准中推荐的方法在全国范围内达成统一。Objective To investigate the awareness of the Radiation Shielding Requirements for Radiotherapy Room–Part 2:Radiotherapy Room of Electron Linear Accelerators(GBZ/T 201.2—2011)among relevant practitioners in medical institutions as well as its implementation and application situation and collect relevant problems and suggestions for an evaluation of the scientificalness,standardization,and timeliness of the standard,and to provide a scientific basis for the further revision and implementation of the standard.Methods An online questionnaire survey was conducted among relevant employees in medical institutions providing medical linear accelerator radiotherapy across 22 provinces of China,which investigated the awareness,training,application,and revision suggestions related to GBZ/T 201.2—2011.The questionnaires were collected and analyzed.Results A total of 340 relevant practitioners filled out the questionnaire.Of the participants,66.80%were physicists;79.11%had an awareness of the standard;56.18%ever participated in the standard-related training;but the survey results showed that the practitioners did not have a good knowledge of the standard’s content,and the training and promotion were not enough;83.24%thought that the standard had been widely used;17.60%thought that the standard needed to be revised;76.76%thought that there was a need to add calculation examples;88.82%thought that neutron shielding needed to be considered for the 10 MV X-ray accelerator room.Conclusion The standard has been widely known in the field of radiotherapy protection.With the development of radiotherapy technology,the standard should be revised to add calculation examples and consider neutron shielding in the 10 MV X-ray accelerator room.The standard is highly technical and difficult to grasp,so the promotion and implementation goals should be appropriate for different personnel groups,the training for employees at key posts should be strengthened,and the methods recommended in the standard should be uniformly used throughout t
