前言 铀的毒理学研究和生产现场职业性危害的调查,国外己积累了较多的资料。大多数学者认为铀是作用於肾脏的化学毒物,辐射危害的可能性不大,并且倾向於主张发生职业性慢性铀中毒的可能性是不存在的。但是,也有某些学者认为铀作用於机体,在近期是化学毒性为主,而远期是取决於电离辐射的作用,职业性慢性铀中毒的可能性是存 Foreword uranium toxicology research and investigation of occupational hazards at the production site, foreign countries have accumulated more information. Most scholars believe that uranium is a chemical poison that acts on the kidneys and is unlikely to be harmful to radiation. And there is no such thing as the tendency to advocate occupational chronic uranium poisoning. However, some scholars believe that uranium acts on the body and is mainly based on chemical toxicity in the near future, while the long-term effect depends on ionizing radiation. The possibility of occupational chronic uranium poisoning is
