µDose performance report

In order to determine the µDose System performance precisely, the results obtained with µDose measurements were compared with other, well-established methods of low-level radioactivity assessment (i.e. TSAC, ICP-OES, HRGS). This research was conducted with the cooperation of five European laboratories and involved measuring a total of 47 sediment samples, including the IAEA reference materials.

Investigation on the impact of 222Ra emanation from reference materials and how it influences HRGS measurements with γBEAKERS

Radon-222 emanation ratios were measured in several IAEA reference materials; for IAEA-RGU-1 emanation ratio was found to be very low (ca. 2.2%) and for IAEA-385, IAEA-375, IAEA-434, IAEA-448 this value was much higher (4%-35%). This analysis was conducted for samples encased in γBEAKERS and immersed in clean wax, and the data for both was compared. Read more https://doi.org/10.1016/j.measurement.2021.109893
