低功率密度微波接触者眼部检查结果分析

Analysis on Eye Examination Results of Workers Exposed to Low Power Density Microwave

目的了解微波对操作人员眼部,晶状体的损伤,为做好健康监护和制定防护措施提供依据。方法依据《职业健康监护技术规范》的要求,对某市企业112名从事微波作业人员进行眼科检查,并将结果与对照组进行对比。结果调查组晶体总混浊率及晶体混浊程度与对照组比较,差异有统计学意义(P<0.01);工龄超过10 a的微波作业人员及45岁以下微波作业人员晶体混浊率均明显高于对照组(P<0.05或0.01),差异有统计学意义。结论长期低强度微波辐射可对工作人员眼晶状体造成损伤,且具有一定的累积作用。应加强对微波作业人员这一特殊群体的健康防护工作,特别是眼部的防护。

[ Objective] To understand the effect of microwave on lens of operators, provide the basis for performing health surveillance and making protective measures. [ Methods ] According to the Technical specifications for occupational health surveillance, the eye examination was conducted in 112 microwave workers, and the results were compared with that of the control group. [ Results]There were significant differences in the total incidence rate and degrees of lens opacity between the investigation group and the control group （P 〈0.01）. The incidence rates of lens opacity of microwave workers whose working age were over 10 years and microwave workers under 45 years old were significantly higher than that of the control group （ P 〈 0. 05 or 0. O1 ）. [ Conclusion]The long-term low power density microwave may damage the lens of operators, and can be accumulated. It is necessary to strengthen the health protection among microwave workers, especially eye protection.
