| 摘要 目的：了解哈尔滨市某三级医院介入人员外照射个人剂量现况和本院辐射防护情况，以期为本院介入防护策略提供一定的科学依据。方法：按照《中华人民共和国国家职业卫生标准》（GBZ128-2016）版本要求，在2016年7月8号～2017年7月8号期间，采用双剂量计监测目标人群年外照射个人剂量，x2检验和logistic回归分析介入人员外照射个人剂量的影响因素。结果：年外照射最小个人剂量为0.08mSv，最大个人剂量为3.60mSv，平均个人剂量为0.23mSv，x2检验表明科室（x2=50.420，P＜0.001）、职业类别（x2=32.992，P＜0.001）、职称（x2=33.806，P＜0.001）和学历（x2=9.289，P＜0.05）有统计学意义；logistic回归分析均表明，职称、工作年限、职业类别进入方程，但只有职称（Wals =4.896，P＜0.05）和职业类别（Wals =8.424，P＜0.05）有统计学意义，医务人员职称和职业类别（Wals =8.424，P＜0.05）是影响个人外照射剂量的因素。结论：本院总体外照射防护措施得当，本院从事介入工作的相关医务人员中，高级职称医务人员外照射个人剂量低于中、低级职称医务人员；技师外照射个人剂量高于护士和医生。根据本研究结果，在医院的外照射防护中应采取一些措施，比如合理分配工作，避免同一工种医务人员长时间暴露于介入相关外照射，避免中低级职称医生长时间接触介入相关外照射，加强医务人员防护意识，适当调整工作岗位，适时进行防护培训。 |

| ABSTRACT Objective: To understand the Personal dose of external exposure and the radiation Protection of hospital Personnel in a tertiary hospital in Harbin, with a view to Providing a scientific basis for our hospital intervention strategy. Methods: According to the requirements of the National Occupational Hygiene Standards of the People's Republic of China (GBZ128-2016), during the Period from July 8, 2016 to July 8, 2017, a dual dosimeter was used to monitor the individual dose of extracorporeal exposure of the target Population, x2 And logistic regression analysis of interventional Personnel external exposure dose factors. Results: Year minimum individual external irradiation dose is 0.08mSv, the maximum individual dose is 3.60mSv, the average individual dose is 0.23mSv, x2 test showed that the Departments (x2 =50.420, P<0.001), medical personnel occupation category (x2=32.992, P<0.001), title (x2 =33.806, P<0.001), and academic qualifications(x2=9.289, P<0.05) (x2 =12.511, P<0.05) with statistical significance; logistic regression analysis indicate the job title, age, occupation the categories in the equation, but only the title (Wals =4.896, P<0.05) and occupation (Wals =8.424, P<0.05) with statistical significance, the medical staff job and occupation categories (Wals =8.424, P<0.05) is the influence factors of personal external exposure dose. Conclusion: The overall external radiation Protection measures in our hospital are appropriate. The individual dose of external exposure to middle and senior Professional titles of the hospital is lower than that of middle and senior Professional titles. The Personal dose of external exposure to technicians is higher than that of nurses and doctors. |
