调查分析了５个铀矿１３３６０名男性职工中癌死亡。观察期自１９７１年１月至１９８５年１２月。肺癌死亡３５名，放射组２４名，对照组１１名．两组肺癌标化死亡率分别为２１．４２×１０－５（放）１５．９４×１０－５（对）．标准死亡比（ＳＭＲ）分别为１·８３（放）和１．４４（对）。放射组标准死亡比有显著意义。放射组肺癌相对危险系数为１．０７％·ＷＬＭ－１。
The survey analyzed cancer deaths among 13360 male workers in five uranium mines. The observation period was from January 1971 to December 1985. 35 patients died from lung cancer, 24 in radiation group and 11 in control group. The standardized mortality rates of lung cancer in the two groups were 21.42×10-5 (put) and 15.94×10-5 (pair), respectively. The standard death rate (SMR) was 1.83 (put) and 1.44 (pair), respectively. The standard mortality ratio in the radiological group was significant. The relative risk of lung cancer in radiation group was 1.07%·WLM-1.
