江西省某典型非铀矿山高氡暴露矿工健康效应现状调查

目的 了解江西省某典型非铀矿山高氡暴露矿工的健康效应现状。方法 采用普查的方法，对≥40岁井下一线工人进行基本情况、氡知晓率的调查，并开展井下一线矿工职业健康检查和肺部低剂量 CT 筛查。结果 井下一线矿工对氡的知晓率仅为3.70%，外周血淋巴细胞染色体畸变分析发现100个细胞畸变率为0%、外周血淋巴细胞微核试验的异常率为0.02‰，眼科检查（晶体裂隙灯检查、玻璃体、眼底）均未见异常，白细胞数异常率为3.70%，肺部小结节检出率为48.15%。结论 高氡暴露井下一线矿工肺部小结节检出率较高，矿工对氡缺乏认知，亟需加强矿工关于氡的危害宣传教育及井下一线矿工的职业病预防控制。

Current health status of high-radon exposure miners in a typical non-uranium mine in Jiangxi Province,China

Objective To investigate the health status of high-radon exposure miners in a typical non-uranium mine in Jiangxi Province, China. Methods A general survey was conducted to investigate the basic situation and awareness rate of radon among underground miners aged ≥ 40 years, and the occupational health examination and low-dose lung computed tomography scan were carried out. Results The awareness rate of radon among miners working down the mine was only 3.70%. The peripheral blood lymphocyte chromosome aberration analysis showed an aberration rate of 0% per 100 cells. The peripheral blood lymphocyte micronucleus test showed an abnormal rate of 0.02‰. Ophthalmic examinations (slit-lamp examination of the lens, the vitreous body, the fundus) showed no abnormality. The abnormal rate of leukocyte count was 3.70%, and the detection rate of small lung nodules was 48.15%. Conclusion The high-radon exposure minors had a high detection rate of small lung nodules, and lack knowledge of radon. It is urgent to strengthen the publicity and education on the hazards of radon and the prevention and control of occupational diseases.
