Title: Draft Radioanalytical Water and Soil Performance Testing Uncertainty Acceptance Criteria Derived From Historical Mixed-Analyte Performance Evaluation Program Results
Published: Date Unknown
Abstract: Radioanalytical performance testing programs provide radioassay laboratories, regulators and the public performance-based evidence that measurement capabilities are in control. Performance acceptance criteria that combine aspects of measurements difference from a known value and the associated combined uncertainty establishes a quantitative statement of statistical confidence. However, there is need for a reasonable upper limit of the reported measurement uncertainty. Evaluation of thousands of historical U.S. DOE Mixed-Analyte Performance Evaluation Program measurement results for 17 radionuclides in soil and water samples provides predictive expectations for future measurement results and a statistical basis for establishing reasonable upper limits for reported measurement uncertainties for performance evaluation programs.
