8. 8 Analytical results are not absolute Uncertainty establishes the range around the result where the true value is expected Inorganic False Positive and Sensitivity Tests Inorganic Uncertainty Reporting

9. 9 No Uncertainty Reported

10. 10 Must Report Numeric Results

11. 11 MAPEP Series 30 False Positives

12. 12 MAPEP Series 30 Sensitivity Evaluations

13. 13 New MAPEP Uncertainty Flags Relative Precision (RP)Flag RP < 2%N 2 < RP < 15%A 15 < RP < 30%W RP > 30%N ■ Uncertainty flags are for information only ■ Series 30 ●~ 82% Uncertainties = A ●~ 10% Uncertainties = N or 30%

14. 14 “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 Frequently Asked Questions

15. 15 Uranium Isotope Results Reported By Alpha & Gamma Spec --Natural-- ------------- Depleted ----------------- ------- Natural-------

16. 16 MAPEP-14-MaS30 Radiological Uranium-238

17. 17 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?
