Plutonium for nuclear weapons was produced at the Hanford Nuclear Reservation from 1944, when it opened, until 1972 when the last reactor was closed. The Hanford Environmental Dose Reconstruction Project (HEDR) estimated that 740,000 curies of radioactive iodine were released to the air from chemical separation facilities used to produce plutonium for atomic weapons and that the majority of releases of iodine-131 occurred between 1944 and 1951 - with 1945 being the year of the highest releases.
