贫铀(depleted uranium,DU)即天然铀加工浓缩后,U235含量低于0.714%的副产品,其中U238占99.75%以上。在海湾战争中北约军队大规模地使用了贫铀弹,其在穿甲过程中形成高浓度颗粒,吸入颗粒后大部分沉积在肺部或转入机体其他系统引起损伤,长期滞留放射毒性和化学毒性可能导致肺部肿瘤形成[1],引发对贫铀的一系列研究[2-4]。研究表明,铀矿尘在诱导大鼠肺组织纤维化过程中铀矿
Depleted uranium (DU) is a by-product of U235 content below 0.714% after natural uranium enrichment, of which U238 accounts for more than 99.75%. During the Gulf War, NATO troops used depleted uranium bullets on a large scale. They formed high concentrations of particles during perforation and most of them were deposited in the lungs or transferred to other systems in the body causing damage. Long-term retention of radiotoxicity and chemical toxicity may Leading to the formation of lung tumors [1], triggering a series of studies on depleted uranium [2-4]. Studies have shown that uranium mine dust in the uranium mine induced lung fibrosis in rats
