摘　　要：目的了解放射工作人员眼晶体损伤状况,为放射防护工作提供技术依据。方法对廊坊市1365名放射工作人员眼晶体进行检查,对结果进行统计分析。结果 1365名放射工作人员中,眼晶体混浊100人,混浊率7.3%;随工龄增长,放射工作人员眼晶体混浊率有增长趋势(χ~2=192.954,P<0.05);医学诊断学、牙科治疗、介入治疗、同位素应用、工业探伤专业的放射工作人员眼晶体混浊率分别为8.7%、1.1%、2.0%、2.5%、8.7%,差别有统计意义(χ~2=15.702,P<0.05);市级医院、县级医院、乡镇医院及其它医疗单位、工业探伤企业的放射工作人员眼晶体混浊率分别为4.0%、5.7%、10.7%、8.7%,差别有统计意义(χ~2=15.728,P<0.05)。结论长期低剂量的职业照射会对放射工作人员眼晶体造成一定损伤,应以乡镇医院及其它医疗单位、从事工业探伤的企业为重点,加强放射防护工作。Objective To understand the status of eye lens damage in radiologic workers in Langfang and provide technical basis for radiological protection. Methods To carry on eye lens examination for 1365 radiologic workers in Langfang,then made statistical analysis on the result. Results 100 out of 1365 radiologic workers be detected as eye lens opacity,the ratio of opacity attach to 7. 3%. The ratio of eye lens opacity of radiologic workers presented a increasing trend with the growth of length of service（ χ2= 192. 954,P 〈 0. 05）. The ratio of eye lens opacity of radiologic workers engaging in medical diagnosis,dental treatment,interventional therapy,isotope application,industrial inspection respectively was 8. 7% 、1. 1% 、2. 0% 、2. 5% 、8. 7%. The difference was statistically significant（ χ2= 15. 702,P 〈 0. 05）. The ratio of eye lens opacity of radiologic workers in municipal hospital,county hospital,health clinics in towns and other medical therapy institution respectively was 4. 0% 、5. 7% 、10. 7% 、8. 7%. The difference was statistically significant（ χ~2= 15. 728.,P 〈 0. 05）. Conclusion Long term low dose occupational exposure will cause some damage to eye lens of radiologic workers. Radiological protection should be enhanced and health clinics in towns and other medical therapy institution and enterprises having to do with industrial inspection work should be regarded as important institution in radiation protection.
