NRC NY Brooklyn American Machine and Foundry Machining of uranium, thorium and zirconium metal plates and rods used to produce nuclear weapons fuel, 1951-54. In 1951, the company machined at least 125 tons of uranium metal. Duration of contract and total quantity of material handled unclear. Operations carried significant potential for raising radioactive dust. No records found on worker exposures, site contamination.
Records suggest operation raised substantial amounts of radioactive dust.
About 20 cubic yards of radioactive waste and debris removed in federal cleanup, 1995. Quantity of materials used and duration of work unclear. Extensive radioactive waste from stacks. Such operations typically raised significant amounts of radioactive dust. A federal survey in 1980 found no evidence of residual contamination at the site.
