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 <2% or >30%

“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

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?
