A surface alpha activity industrywide study was conducted at the Portsmouth Gaseous Diffusion Facility (SIC-2819), Piketon, Ohio, as part of a response to a request from the Oil, Chemical, and Atomic Workers International Union for a cohort mortality study. The facility, operated under contract to the Department of Energy (DOE), was involved in enrichment of uranium-235 (15117961) in uranium- hexafluoride gas for nuclear power and national defense purposes. A removable alpha surface activity survey was conducted as a cross check of urinalysis data. Methodology involved comparing the numerical order in decreasing value of building geometric mean removable alpha values with a numerical order of calculated urine alpha value indices associated with departments in the buildings. For all surfaces measured, activity levels in the six buildings were well below the derived surface contamination limit. However, several locations were noted where surface measurements exceeded action level criteria of Goodyear Atomic Corporation and DOE. The authors conclude that removable alpha surface contamination does not contribute significantly to internal radiation dose at this site and that the urine alpha data base can be used to define relative exposure groups. Recommendations are made regarding those areas which should be considered for additional emphasis in the contamination control program, and suggested methods are given for data analysis for workplace surveillance.
