The U. S. Department of Energy’s Mixed-Analyte Performance Evaluation Program (MAPEP)FY 2014 Review Shane Steidley DOE Radiological and Environmental Sciences Laboratory ASP Meeting 2014 Sept. 18, 2014
MAPEP Series 29-30 Overview • MAPEP Participant Policy • Participating Laboratories • Inorganic Uncertainties • Strontium 89/90 Air Filter • Certified Reference Materials Update
MAPEP Participant Policy • Agree to abide by MAPEP’s System or Export Control Agreement • Labs notified if: • MAPEP standards are returned to RESL • Results are not reported in two Series • Non-responding labs will be deactivated
Export Control Agreement Export Control Agreement = System Usage Agreement
Inorganic Uncertainty Reporting • Analytical results are not absolute • Uncertainty establishes the range around the result where the true value is expected • Inorganic False Positive and Sensitivity Tests
New MAPEP Uncertainty Flags • Uncertainty flags are for information only • Series 30 • ~ 82% Uncertainties = A • ~ 10% Uncertainties = N or <2% or >30%
Frequently Asked Questions • “Can I just report my MDL?” • Report the calculated result and total uncertainty • “Can I report a less than value?” • No, non-numeric results are not allowed • “What if I’m contractually obligated to use a specific procedure?” • The laboratory is responsible to ensure the procedure they use produces accurate results
Uranium Isotope Results Reported By Alpha & Gamma Spec --Natural-- ------------- Depleted ----------------- ------- Natural-------
Performance Evaluation of Sr-89/90 in Series 31 Air filter • Many requests for performance testing of fresh fission products • Renewed interest since Fukushima • Sr89/90, I-131, Zr-95/Nb-95, etc. • Twenty-three laboratories request the Sr-89/90 Air Filter • 12 requested Sr-89 out of 32 who routinely analyze Sr-90 • 11 who don’t report Sr-90, requested SrF31 • Do all 32 labs have analytical capability in Sr-89? • Is there a continued interest in Sr-89/90 or other fresh fission products determinations?
