2013-2015年广东省某核电站放射工作人员眼晶状体情况

Status of eye lens among radiation workers in a nuclear power plant of Guangdong Province from 2013-2015

目的分析广东省某核电站放射工作人员眼晶状体的健康状况,为更好地推进职业健康防护提供科学依据。方法选择在2013—2015年于深圳市职业病防治院进行职业健康检查的核电站放射工作人员的眼晶状体检查资料,分析3年的变化。结果 2013—2015年放射工作人员的晶状体混浊率分别为4.13%、4.96%、4.47%,差异无统计学意义(P>0.05);2015年晶状体混浊率(4.47%)与对照组(1.95%)相比较,差异有统计学意义(P<0.05);不同工龄放射工作人员间比较,差异无统计学意义(P>0.05);随着年龄的增加,眼晶状体混浊率增高,不同年龄间比较,差异有统计学意义(P<0.05)。结论该核电站放射工作人员长期接触低剂量放射性对眼睛晶体的伤害仍然存在,做好眼睛的防护至关重要,需加强核电站放射工作人员辐射防护,定期组织健康检查,做到早发现早治疗。

[Objective]To analyze the health status of eye lens among radiation workers in a nuclear power plant of Guangdong Province,provide a scientific basis for improving the occupational health protection.[Methods]The eye lens data of radiation workers in a nuclear power plant,who have received the occupational health examination in the Prevention and Treatment Hospital for Occupational Disease of Shenzhen from 2013-2015,were collected to analyze the changes in 3 years.[Results]From 2013 to 2015,the rate of lens opacities in radiation workers was respectively 4.13%,4.96% and 4.47%,and the difference was not statistically significant（P〉0.05）. In 2015,the difference in the rate of lens opacities between the radiation workers（4.47%） and the controls（1.95%） was statistically significant（P〈0.05）. There was no statistically significant difference among workers with different length of service（P〉0.05）. The rate of lens opacities increased with age,and the difference was statistically significant among different age groups（P〈0.05）.[Conclusion]Long-term low-dose radiation exposure has caused harm to the eye lens among radiation workers in the nuclear power plant,and the eye protection is critical. It is necessary to strengthen the radiation protection among workers in nuclear power plant and carry out the regular medical examination to ensure early detection and early treatment.
