Zusammenfassung:
The interlaboratory comparison (ILC) described in this document was performed in the framework of Work
package 3 of the MetroPOEM project. Two traceable candidate reference materials (RM) were prepared by spiking a matrix with 234U, 235U, 236U, 238U, 239Pu, 240Pu, 241Am and 237Np, and were measured by participants using mass spectrometry and radiometric techniques. For the liquid RM used in the liquid ILC, the matrix was natural seawater, while for the solid RM used in the solid ILC, the matrix was a synthetic sand obtained by a sol-gel process. The measurands selected were the mass fraction of 238U, 239Pu, 241Am and 237Np, and the 234/238U, 235/238U, 236/238U and 239/240Pu isotope ratios. The liquid comparison involved 11 participants, who produced a total of 83 results. The solid comparison involved 11 participants who produced a total of 79 results. This report presents the characteristics of the liquid and solid RM used, and the assigned values for each measurand, the results of the participants and their analysis following statistical criteria and eventually the comparison of the experimental procedures of the participants. This report will be updated after publication, to include additional results from participants who did not have time to submit, and the analyses and comments will be updated accordingly. |
