在铀矿开采作业中 ,工作人员会吸入铀的子代产物、氡和氡子体气溶胶、氡的短寿命子体2 18Ｐｏ和2 14 Ｐｂ ,对呼吸道上皮形成α辐射 ,从而诱发肺癌。美国、加拿大、捷克等国家 ,相继报道了铀矿工肺癌流行病学的调查结果 ,6 0～ 70年代后世界许多非铀矿山氡的危害越来越受到各界 In uranium mining operations, workers inhale uranium progeny products, alfalfa and radon progeny aerosols, and the short-lived daughters 2 18Po and 2 14 Pb of alfalfa to form α-radiation on the respiratory epithelium, thereby inducing lung cancer. The United States, Canada, the Czech Republic and other countries have reported the results of the investigation of the lung cancer epidemiology of uranium miners. After the 1970s and the 1970s, the hazards of many non-uranium mines in the world have been increasingly affected by
