摘要
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。
Lung cancer among 13 360 maleworkers of 5 uranium mines were investigated'.During the period of observation(Jan. 1971-Dec. 1985 ) 35 lung cancerswere registered: among them 24 were inexposed group and 11 in control group.Standard mortality of lung cancer forthese two groups were 21 .42· 10-5 and15. 94· 10-5, respectivly. SMR were 1. 83(exposed group)and l' 44 (control group)(p<0.01 ). The average latent periodof lung cancer in exposed group was17. 5 years, and the average cumulativeexposure dos3 to radon daughters was168 WLM.The average age of workersdead of lung cancer was 47. 83 years.The excess RR coefficient of lung cancerwas 1 .07%/WLM. SMR increased withincreasing cumulative exposure dose toradon daughters. The adjusted mortalityof long cancer of smokers in exposedgroup was obviously higher than thatof nonsmokers.
