宁夏9家医疗机构放射工作人员健康状况调查

Investigation on Health Status of Radiation Workers of 9 Medical Institutions in Ningxia

目的了解长期暴露于低剂量辐射环境中的医务工作人员的健康状况,为职业健康监护工作的科学管理提供依据。方法收集宁夏银川市9家医疗机构放射工作人员健康检查表,并对体检结果进行分析。结果银川市2014年9家医疗机构96.5%放射工作人员的外照射个人剂量小于5 mSv,不同放射工种间,介入放射学工作人员的外照射个人剂量高于诊断放射学、核医学和放射治疗的工作人员;各工龄组间外照射个人剂量差异无统计学意义。不同工种间血常规、肝功能和肾功能各指标异常率差异无统计学意义;不同工龄间,≥20年组工作人员白细胞异常率较其他组高,10年~组ALT和AST异常率较其他组高。结论放射工作人员职业外照射个人剂量处于较低水平,长期小剂量电离辐射可能对放射工作人员的造血系统和肝功能有不良的影响。

Objective To understand the health status of medical workers who exposed to radiated environment of low doses in long- term and to provide the basis for scientific management of occupational health surveillance.Methods To collect the radiation workers health check lists of 9 Medical Institutions in Yinchuan city and the physical examination results were analyzed.Results 96.5%radiation workers' the personal doses were less than 5 mSv of 9 medical institutions in Yinchuan city in 2014.compared with the personal doses of different radiation types the doses of the dose of the intervention group were significantly higher than those of the diagnostic radiology group,nuclear medicine group and radiation therapy group;External irradiation dose among different service length group has no of staffs statistical significance.The abnormal rates of the index of blood routine,liver function and kidney function among different types have no statistical significance;In different service length group,the staffs of ≥20 years group's abnormal rates of white blood cell were significantly higher than other groups,10 years service group' s abnormal rates of ALT and AST were significantly higher than other those of groups.Conclusion Radiation workers external dose at a low level,long- term and low- dose ionizing radiation may have an adverse effect on the hematopoietic system and liver function of radiology staff.
