Radionuclide Certified value^a [Bq kg^-1]

Radionuclide Information value [Bq kg-1]

a The value is the robust mean (estimated in accordance with ISO 13528 [6]) of accepted sets of data. The certified values are reported on dry mass basis and are traceable to the SI.

b Expanded uncertainty with a coverage factor k=2 estimated in accordance with ISO 13528.

c 210Pb and ²¹⁰Po were considered as in equilibrium

TABLE 2. HOMOGENEITY TESTS ^(*) FOR RADIONUCLIDES IN IAEA-410

(*) Normalized activity =x/X (individual/mean values). The homogeneity test was performed in RML (organizer of this characterization study) for different radionuclides using different techniques such as gamma-, alpha- and beta spectrometry as well as mass spectrometry, before dispatch of samples (see more detail in homogeneity test).

(^) Laboratory reported that the sample is inhomogeneous for Pu isotopes when 9 aliquots of samples at different masses (0.5;

1; 3; 5 g) were analysed using normal/partly leaching digestion technique (as requested by laboratory, the data here is the mean value of 4 homogeneous values done for 3 g only). However, the second analysis of sample (6 aliquots of 0.5 1g) using total digestion with HF/HNO3 and boric acids/HCl gave homogeneous data, resulting that the non-homogeneity of samples could be due to the leaching techniques (which is confirmed by IAEA and CNA in Seville for further investigation using two different leaching methods and then measured sample by AMS technique, see detail in the report).
