PPT-Missing Matter in a Uranium Mine

The Oklo Phenomenon Initial Problem 1972 A worker notices that the isotopic composition of mined uranium from the Oklo site is missing Uranium 235 Initial Problem 1972 The collection of uranium is regulated to ensure that it is not being siphoned off into weapons programs This lead to further investigations of the missing mass. Depleted uranium is one of the byproducts of uranium enrich ment and like any other uranium compound has both chemi cal and radiological toxicity Depleted uranium is only slightly radioactive 60 per cent as radioactive as natural uranium Depleted ur Uranium-235In addition to the uranium stored at nuclear reactors (theU.S. inventory is shown in Figure 1), there are about 2,000tons of highly enriched uranium in the world, producedmostly for nuclear Part III:.
