The Norton Company is an AWE facility from 1945-March 1, 2011 and a beryllium vendor from 1944-1956 so workers are eligible to file Part B claims for the appropriate years.
Norton has two Special Exposure Cohorts which covers all workers with specific cancers and at least 250 days of employment for January 1, 1945-October 10, 1962.
Norton manufactured refractory products from boron, beryllium, uranium, thorium, and magnesium oxide for the MED and the AEC.
As early as 1943, Norton was providing boron to the SAM laboratory. Documents show that Norton began working with beryllium for the MED in approximately September 1944 and that work with beryllium continued through 1956. Work with thorium and uranium continued through 1957 at Norton's Worcester location.
Norton continued to manufacture refractory products until at least 1965 for the AEC weapons complex, including Rocky Flats, Hanford and Y-12. However, after 1957 these contracts specified that the refractory products were to be made out of magnesium oxide. Since magnesium oxide is not radioactive, Norton's work with it does not qualify it as an Atomic Weapons Employer for these years.
During the period of residual contamination, as designated by the National Institute for Occupational Safety and Health and as noted in the dates above, employees of subsequent owners and operators of this facility are also covered under the Energy Employees Occupational Illness Compensation Program Act.
DOE Legacy Management has a Norton webpage because it was considered for FUSRAP.
