9 No Uncertainty Reported
10 Must Report Numeric Results
11 MAPEP Series 30 False Positives

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 “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

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?
