摘要
目的了解淮安市长期接触低剂量电离辐射对放射工作人员眼晶状体的损伤情况。方法用裂隙灯检查306名医疗机构放射工作人员和105名非放射工作人员眼晶状体混浊情况并对结果进行分析。结果放射工作人员眼晶状体混浊率为12.75%,高于非放射工作人员(P<0.01),不同年龄、工龄放射工作人员眼晶状体混浊率比较,差异有统计学意义(P<0.01);不同工种放射工作人员眼晶状体混浊率比较,差异无统计学意义(P>0.05)。结论长期小剂量电离辐射受照可以导致放射工作人员晶状体混浊概率增高,应加强对该市医疗机构放射工作人员的防护。
[Objective]To estimate the prevalence of lens opacity among radiation workers exposed to long-term low-dose ionizing radiation in Huaian City.[Methods]306 radiation workers in medical institutions and 105 non-radiation workers were detected by the slit lamp to investigate the status of lens opacity, and the results were analyzed. [Results]The rate of lens opacity in radiation workers was 12.75%, which was higher than that in non-radiation workers（P〈0.01）. There were significant differences in the rate of lens opacity among radiation workers in different age, length of service groups （P〈0.01）. The difference in the rate of lens opacities among radiation workers in different work type groups was not significant （P〉0.05）.[Conclusion]Exposure to long-term low-dose ionizing radiation can cause the increasing risk of lens opacity in radiation workers. It is necessary to strengthen protection among radiation workers in medical institutions of Huaian City.
