摘　　要：目的随着我国养宠物家庭的增多,动物医院也以每年19.86%的水平增加。但是多部门监管可能存在的管理盲区,导致动物医院放射工作人员的从业环境显著差于医疗机构。本研究通过了解我国动物医院放射工作人员职业外照射剂量水平,分析动物医院放射工作人员存在的职业风险,以保障从业人员的职业健康,为国家制定相关法规标准提供数据基础与科学依据。方法数据来自国家个人剂量登记系统,采集的信息包括2022年我国部分动物医院放射工作人员个人剂量监测数据等。结果本研究涉及全国28个省市的1216家动物医院1868名放射工作人员,最大年有效剂量为8.93 mSv,集体剂量为536.77 man·mSv,人均年有效剂量为0.29 mSv,中位数为0.15 mSv;<1.0 mSv的人员占比最高为94.5%,其次为1.0~<5.0 mSv(5.4%)。动物医院>1.0 mSv的个人剂量人员分布比显著高于医学应用和工业应用(P<0.05)。结论动物医院放射工作人员职业外照射水平符合国家标准要求,但仍应重视动物医院放射工作人员的放射防护工作,如强化动物医院业主的主体责任意识、加强放射工作人员的防护培训,保障从业者职业健康,预防职业性放射性疾病的发生。Objective With the increase in pet-owning households in China,veterinary clinics have increased at an annual rate of 19.86%.However,the management blind area that may exist in multi-department supervision has led to a significantly worse working environment of radiation workers in veterinary clinics than that of medical institutions.The purpose of this study was to understand the levels of occupational external exposure of radiation workers in veterinary clinics in China,analyze the occupational risks faced by radiation workers in veterinary clinics,contribute to the protection of the occupational health of radiation workers,and provide data and scientific basis for the formulation of national relevant regulations and standards.Methods The individual dose monitoring data of radiation workers in selected veterinary clinics in 2022 were obtained from the National Individual Dose Registration System.Results This study involved 1868 radiation workers from 1216 veterinary clinics in 28 provinces and municipalities in China.The maximum annual effective dose was 8.93 mSv,the annual collective dose was 536.77 man·mSv,the average annual effective dose was 0.29 mSv,and the median was 0.15 mSv.The largest proportion of individuals(94.5%)received a dose of less than 1.0 mSv,while 5.4%had doses ranging from 1.0 mSv to less than 5.0 mSv.For radiation workers with an annual effective dose of 1.0 mSv and above,the individual distribution ratio of radiation workers in veterinary clinics was significantly higher compared with those in medical institutions and industrial applications(P<0.05).Conclusion The levels of occupational external exposure of radiation workers in veterinary clinics meet the requirements of national standards.However,attention should still be paid to the radiation protection of radiation workers in veterinary clinics.This includes enhancing the responsibility awareness of veterinary clinic owners,strengthening protection training for radiation workers,protecting the occupational health of practitioners,and p
