Objective: To investigate the application of GBZ/T 220.2-2009 "The Specification of Radiological Protection Assessment for Occupational Hazard in Construction Project-Part 2: Radiotherapy Facility" in health management institutions, and to understand the scientificity, practicability and problems existing in the implementation of the standard. Methods: The method of multistage stratified sampling and questionnaire survey were used to collect the standard application status among 96 radiological health managers who had participated in the evaluation of radiotherapy facility construction projects in 6 provinces and cities from November 2020 to April 2021. A descriptive statistical analysis method was used to analyze the basic information of the survey object, the knowledge of the standard, the publicity and implementation of the standard. Results: The radiological health management personnel mainly came from health supervision agencies (62.5%, 60/96) , and 86.5% (83/96) were engaged in the pre-evaluation of radiotherapy device construction project and the approval and supervision of control effect evaluation. The awareness rate and training rate of radiological health managers on GBZ/T 220.2-2009 were 88.5% (85/96) and 31.3% (30/96) , respectively. 89.6% (86/96) managers thought it could meet the needs of radiotherapy facility construction project approval or supervision. 49.0% (47/96) of managers believed that the standard needed to be revised. Conclusion: The content of GBZ/T 220.2-2009 is basically scientific and reasonable, but the publicity, implementation and training of radiological health administrator still need to be strengthened. It is suggested to revise some clauses in the standard that do not meet the requirements.
目的： 调查GBZ/T 220.2-2009《建设项目职业病危害放射防护评价规范 第2部分：放射治疗装置》（简称"GBZ/T 220.2-2009"）在卫生管理机构中的应用情况，了解标准的科学性、实用性和实施过程中存在的问题。 方法： 采用多阶段分层抽样的方法，于2020年11月至2021年4月选取全国6个省市参与过放射治疗装置建设项目评价的放射卫生管理人员96人开展问卷调查。采用描述性统计分析方法对调查对象的基本情况，对标准的知晓、宣贯和执行情况等进行分析。 结果： 放射卫生管理人员主要来源于卫生监督机构（62.5%，60/96），86.5%（83/96）的管理人员从事过放射治疗装置建设项目预评价和控制效果评价审批或监督管理工作。放射卫生管理人员对GBZ/T 220.2-2009的知晓率和培训率分别为88.5%（85/96）和31.3%（30/96）；89.6%（86/96）的管理人员认为标准能够满足放射治疗装置建设项目审批或监督工作的需要，49.0%（47/96）的管理人员认为标准需要修订。 结论： GBZ/T 220.2-2009内容基本科学合理，但仍需要加强对放射卫生管理人员的宣贯和培训，建议对标准中部分不适应要求的条款进行修订。.
