Editing Uranium (section)

===Effects and precautions===
Normal functioning of the [[kidney]], [[brain]], [[liver]], [[heart]], and other systems can be affected by uranium exposure, because, besides being weakly radioactive, uranium is a [[Metal toxicity|toxic metal]].{{sfn|Emsley|2001|p=477}}<ref name="Craft04">{{cite journal

Although accidental inhalation exposure to a high concentration of [[uranium hexafluoride]] has resulted in human fatalities, those deaths were associated with the generation of highly toxic hydrofluoric acid and [[uranyl fluoride]] rather than with uranium itself.<ref>{{cite book |url=https://books.google.com/books?id=qDf3AO8nILoC&pg=PA1468 |page=1468 |title=Medical Toxicology |author=Dart, Richard C.|publisher=Lippincott Williams & Wilkins |date=2004 |isbn=978-0-7817-2845-4}}</ref> Finely divided uranium metal presents a fire hazard because uranium is [[pyrophoricity|pyrophoric]]; small grains will ignite spontaneously in air at room temperature.<ref name="LANL" />
