Results of the independent radiological verification survey at B and T Metals, 425 West Town Street, Columbus, Ohio (CO001V)

Abstract

In the mid-1940s, B and T Metals, 425 West Town Street, Columbus, Ohio became one of the first commercial firms to provide extrusion of uranium billets into rods in support of Manhattan Engineer District (MED) operations. The US Department of Energy conducted radiological surveys of these sites to evaluate current radiological conditions as part of the 1974 Formerly Utilized Sites Remedial Action Program (FUSRAP). In 1988 and 1989, a preliminary radiological survey was conducted by ORNL on the commercial property of B and T Metals. Results of the survey indicated that limited and localized residual radioactive material found in the main building and in one area outdoors exceeded current DOE guidelines, and the site was recommended for remediation. In the spring of 1996, a radiological verification survey of this property was conducted by ORNL, the independent verification contractor, in conjunction with decontamination operations conducted under the supervision of Bechtel National, Incorporated. The verification survey included gamma scans of the main building and parts of the grounds, limited beta-gamma scans of the building and roof, limited alpha scans of inside overhead structures, smear sampling, and the collection of samples for radionuclide analysis. This report describes the results of the radiological verification survey of the commercial property of B and T Metals, Columbus, Ohio.
