RE: Source for Uranium Nitrate
Dick, I am realy surprised by your reply...I will not..oude koeien uit de sloot halen....(dutch verb)..but: I do think that the stuff should NOT be treated lightly: http://en.wikipedia.org/wiki/Uranyl_nitrate Health and environmental issues Uranyl nitrate is an oxidizing and highly toxic compound and should not be ingested; it causes severe renal insufficiency and acute tubular necrosis and is a lymphocyte mitogen. Target organs include the kidneys, liver, lungs and brain. It also represents a severe fire and explosion risk when heated or subjected to shock in contact with oxidizable substances. http://physchem.ox.ac.uk/MSDS/UR/uranium_nitrate.html Toxicology Toxic by inhalation or ingestion. Should be treated as a potential carcinogen. May cause mutagenic or teratogenic effects. Danger of cumulative effects. Caustic, corrosive. Yyes, yes, ofcourse Mark will not eat it, but nevertheless...
