Abstract |
The report contains the results of the Analytical Sciences Branch (CRD-LV) Performance Evaluation Study for Blind-B; October 17, 1995. The known value for each analysis was determined by gravimetric methods, checked by chemical analyses performed by CRD-LV's Radiochemistry Laboratory, and compared to the participating laboratories' grand average. The expected precision, determined by the known value, was taken from 'Table 2. Laboratory Precision: On Standard Deviation Values and Control Limits for Various Analyses', which is based on data accumulated over the years by the Performance Evaluation Program, and can be found in the Environmental Radioactivity Performance Evaluation Studies Program and Radioactive Standards Distribution Program information brochure. |
