Since the early 1940’s some radioisotope separation has been intermittently performed in the calutrons located at Oak Ridge, uranium being the most notable. With minor modifications being made to the equipment, Th230 also has been separated. In 195

In its inception, the electromagnetic plutonium separation facility was constructed to provide small, research quantities of the isotopes. Feed was limited and the content of isotopes other than Pu239 was quite low. Thus health problems were those as
