【摘要】：[目的]了解乌鲁木齐市医疗机构X射线放射工作人员2010—2013年职业性外照射受照剂量水平,为放射防护工作提供科学依据。[方法]以乌鲁木齐市41家医疗机构373名X射线放射工作人员为研究对象,用热释光个人剂量测量方法测定个人剂量,并按国家标准GBZ 128—2002《职业性外照射个人监测规范》对检测结果进行评价,用方差分析等方法对不同年份、不同级别医疗机构、不同工种X射线放射工作人员个人剂量监测结果进行统计学分析。[结果]2010—2013年乌鲁木齐市医疗机构X射线放射工作人员各年的人均年有效剂量均低于国家标准所规定的20 m Sv的限值。不同医疗机构之间,三级医疗机构X射线放射工作人员人均年有效剂量最高(0.97±0.54)m Sv,二级医疗机构次之(0.91±0.23)m Sv,一级医疗机构最低(0.71±0.22)m Sv。不同工种之间,医用放射工作人员人均年有效剂量从大到小排列依次为介入放射学操作(1.39±0.62)m Sv、X射线摄影(0.85±0.28)m Sv、牙科诊断(0.65±0.22)m Sv。[结论]乌鲁木齐市X射线放射工作人员的个人受照剂量监测结果在不同年份、不同医疗机构以及不同工种之间存在一定差异,但均低于我国放射卫生防护标准。
[Abstract]:[objective] to understand the radiation dose level of X ray radiation workers in medical institutions in Urumqi from 2010 to 2013, and to provide scientific basis for radiation protection. [methods] 373 workers of X-ray radiation in 41 medical institutions in Urumqi were studied. The personal dose was measured by thermoluminescence personal dosimetry. According to the national standard GBZ 128-2002, the test results were evaluated, and the medical institutions of different levels in different years were analyzed by means of ANOVA. The individual dose monitoring results of X-ray radiation workers in different types of work were analyzed statistically. [results] the annual effective dose of X-ray radiation workers in Urumqi medical institutions from 2010 to 2013 was lower than the limit of 20 m Sv stipulated by the national standard. Among different medical institutions, the average annual effective dose of X-ray radiation workers in tertiary medical institutions was the highest 0.97 卤0.54 mSv, followed by second-level medical institutions 0.91 卤0.23mSvand the lowest level of 0.71 卤0.22mSv. The average annual effective dose of medical radiation workers ranged from large to small in the order of interventional radiologic operation 1.39 卤0.62mSv-X ray radiography 0.85 卤0.28mSvand dental diagnosis 0.65 卤0.22mSv. among different types of work, the order of annual effective dose per person was 1.39 卤0.62mSv-1, 0.85 卤0.28mSvand 0.65 卤0.22mSv, respectively. [conclusion] the individual radiation dose monitoring results of X-ray workers in Urumqi are different in different years, different medical institutions and different types of work, but all are lower than the standards of radiation health protection in China.
