摘　　要：目的探讨低剂量电离辐射对从业者眼晶体损伤的影响。方法对成都市1032例放射从业者的累积剂量与眼晶体损伤作相关分析。统计分析采用SPSS 16.0作Wilcoxon秩和检验、χ^2检验及多因素Logistic回归分析。结果在男性、女性及年龄≥35岁组内,累积剂量≥11.369 mSv组的晶体异常率均高于〈2.009 mSv和2.009-11.369 mSv剂量组（P〈0.05）;以累积剂量分层,不同性别及年龄组间眼晶体指标分布无统计学差异（P〉0.05）。控制性别、工种及年龄混杂因素后累积剂量（≥11.369 mSv）是晶体损伤的主要危险因素（OR=7.78,95%CI：1.93-31.38）。结论长期接触低剂量电离辐射对从业者眼晶体有一定的损伤作用。Objective To explore the impact on eye lens among workers exposed to low- dose ionizing radiation. Methods1032 subjects were used to analyze the correlation between the accumulated radiation doses and eye lens damage. Wilcoxon Rank,χ^2Test and Multivariate Logistic Regression were implemented with SPSS16. 0 software. Results Both in male,female and those over 35 years,the abnormal rate of Eye Lens in accumulated doses over 11. 369 mSv was higher than that of the group with doses less than 2. 009 mSv（ P〈0. 05）. There was no statistical difference between the eye lens distribution in male and female groups with the stratification factor of accumulated doses（ P〉0. 05）. And there was no statistically significant difference between the eye lens distribution in thoser under 35 years and over 35 years with the stratification factor of accumulated doses（ P〉0. 05）. The accumulated dose which was more than 11. 369 mSv was the major risk factor for the damage of Eye Lens with controlling confounding factors such as gender,work- type and age（ OR = 7. 78,95% CI： 1. 93 - 31. 38）. Conclusion Long- term exposure to low- dose ionizing radiation has certain damage on Eye Lens of occupational population.
