In my opinion Wikepedia is a poor source for scholarly, accurate material, especially assesment of dangers. It is not that it never contains scholarly, well-documented and well-researched material. It is simply because anyone can add to it. That includes self-styled experts that really don’t know the subject matter.
I would suggest that you read the IAA Article appearing in the IAA Journal Issue 434, Nov/Dec 2003, pages 20 and 21, entitled “Denal” - “DE”-“Depleted Uranium”: A Warning," by Fred Davis. I actually submitted this article on behalf of Fred, who indicated he had broached the subject with IAA before with no reply nor any mention in their publications, and felt that he might be sending it to the wrong people.
I submitted this to Chris Punnett on August 13, 2003, with the following opening paragraph to my letter of submittal:
“Enclosed herewith is a letter addressed to you, but sent to me for review, by my dear friend Fred Davis, on a matter of much concern to him. It is also of concern to me, after reading his letter and enclosures, and reviewing my own, fairly substantial file on DU munitions.”
Fred is a retired professional chemist, who was with the Port of San Francisco U.S. Customs Laboratory. He had military service in Germany during the cold war, I believe in the Medical Core. He has a degree in Chemistry, and as he said in his letter, which was published as an article, forty years of hands on experience in the field, including dealing with known and potentially radioactive materials. He is, in short, a professional in the field, and agree or not. his article is a scholarly review of the hazards involved with, among other things, the sectioning of DU cores.
aAnyone interested in a professional view of the dangers inherent to DU should read this article. If so requested, and approved by Chris Punnett, I will scan the article and have it put onto the forum.
Falcon - you are correct about DU being pyrophoric. Finely divided Uranium can ignite spontaneouly in air. That is briefly covered in the cited article.
