目的了解铀矿工矽肺发病情况规律与特点，综合评价铀矿工矽肺防治效果。方法对３个铀矿和两个铀矿地质勘探队进行流行病学调查研究。结果所有矽肺病例开始接尘时间均在五六十年代。自建矿、建队以来的３０多年中，粉尘浓度、矽肺检出率呈下降趋势，矽肺发病工龄、发病年龄、晋期年限、病程与死亡年龄均呈延长趋势。晚发矽肺比例为２０．３１％。只有铀矿粉尘接尘史的矽肺病例平均发病工龄７．４７年，平均发病年龄３６．７４岁，短于有其他非铀矿粉尘接尘史的混合接尘矽肺病例。结论铀矿工矽肺综合防治效果显著。只有铀矿粉尘接尘史的矽肺病例平均发病工龄短，平均发病年龄较轻
Objective To understand the rules and characteristics of silicosis in uranium miners and to evaluate the effect of preventing and treating silicosis of uranium miners. Methods Epidemiological investigation of three uranium mines and two uranium geological exploration teams was conducted. Results All silicosis cases began to catch dust in the fifties and sixties. Over the past 30 years since its establishment, the dust concentration and the detection rate of silicosis have been on a downward trend. The length of service, the age of onset, the length of the promotion, the duration of illness and the age of death are all increasing. Late silicosis rate of 20.31%. The average incidence of silicosis cases with a history of uranium dust dust exposure was 7.47 years, with an average age of 36.74 years, which was shorter than the cases of mixed dust silicosis cases with other non-uranium dust dust exposure history. Conclusion The comprehensive prevention and cure of silicosis of uranium miners is remarkable. Only the history of uranium dust dust exposure to silicosis cases average length of service shorter, the average age of onset is light
