Hanford's Air Releases
Most of Hanford's air releases were from the chemical process used to separate plutonium and uranium from fuel rods. Some of the air releases came from the nuclear reactors. The major radioactive releases occurred between 1944 and 1957. The largest releases were between December 1944 through 1947, when there were no filters on the stacks of the separations plants. Radioactive materials in the form of gases, vapors, and particles were released. Left picture: B-reactor.
