Hanford is a DOE site from 1942 to the present so claimants may file both Part B and Part E claims.
Hanford has four Special Exposure Cohorts that cover all workers with specific cancers and with at least 250 days employment from October 1, 1943-December 31, 1983 and other dates depending on contractor.
Hanford was established in 1942, as a major government-owned nuclear weapons production site, fabricating reactor fuel, operating nine nuclear material production reactors and building five major chemical separation plants, and producing plutonium for nuclear weapons. Later operations also included nonmilitary applications of nuclear energy. In 1965, the laboratory functions performed at Hanford were separately identified as Pacific Northwest Laboratory (renamed Pacific Northwest National Laboratory in 1995) and were operated by Battelle Memorial Institute. This work took place on the premises of the Hanford site through the end of 2004. Beginning in 2005, Battelle also began operating a separate facility in Richland where some on these laboratory functions were performed.Throughout the course of its operations, the potential for beryllium exposure existed at this site, due to beryllium use, residual contamination, and decontamination activities.
NIOSH has done a number of dose reconstructions on Hanford workers. NIOSH has also developed Hanford technical basis documents and Hanford currently has five Special Exposure Cohorts for October 1 1943 through June 30, 1972.
