OH Cincinnati John Van Range Limited testing of stamping techniques on uranium metal, 1956. Records suggest minimal potential for radioactive contamination. Eliminated OH Cincinnati Magnus Brass Machining of at least 200 uranium metal ingots, 1954-57. Approximately 17 tons of natural uranium metal used to test boring equipment. Some decontamination work was done after the tests, slightly contaminated coolant left for company use.
Records suggest workers faced substantial radioactive and toxic exposures.
Properties redeveloped after work ended. Grasselli Research Laboratory Testing of methods for fabricating uranium metal cylinders, early 1940s. No waste disposed of on site. 1976 survey found no significant contamination. Records show extremely high worker exposures to radioactive dust and toxic fumes.
