Letter report: Radiological analysis of Oak Ridge Y-12 plant groundwater data
- H and R Technical Associates, Oak Ridge, TN (United States)
The Y-12 Plant groundwater radiological data bases have been analyzed to determine whether historical and current data is suitable for unqualified release to various user groups. User groups include those who routinely compare results to reference standards or regulatory levels, conduct hydrogeological transport studies, conduct statistical analyses and conduct risk assessment studies. The overall methodology used for the radiological analysis is to check whether results are consistent with chemical and physical expectations, plant operational history and, where applicable, with results from other sites. For example, the relationship among isotopes in a decay chain are predictable if no unusual sources for a particular isotope in the chain exists, the time history is known, and differential removal or concentration mechanisms for a particular isotope are understood or do not exist. Similarly, background concentrations for radioisotopes (e.g., {sup 238}U, {sup 234}U, {sup 235}U, {sup 230}Th, {sup 226}Ra, etc.) should be consistent with those obtained in other studies given similar mineralogical or hydrogeological conditions at the Y-12 Plant. If the analysis results in lack of agreement between results and expectations based on known relationships, plant operations and transport parameters, then results are investigated further.
