“…Foodstuff samples as milk powder, drinking water and bilberry powder were already used. The bilberry material is one of the newest certified reference materials (IRMM-426), which can be used for the validation of radionuclide measurement methods at the monitoring laboratories [ 15 ]. The aim of the inter-laboratory comparisons is not only to evaluate the results obtained from the laboratories, but also to help them to improve their measurements and methods via workshops and meetings.…”

The Member States (MS) of the European Union (EU) are obliged to monitor the radioactivity in the environment since the signature of the Euratom Treaty (Treaty establishing the European Atomic Energy Community). Numerous secondary legislations derived from the Treaty can be found stating restrictions and maximum permitted levels of radionuclides in foodstuff. But to that purpose, no common integrated measurement methods are used with well-defined measurands. The present work consists of two parts. First, the current European regulations in force were collected, and then the food monitoring results, provided by the MS, were analysed.

“…The separation of Sr and its purification, however, were performed using widely varying procedures. [12] Co-precipitation of Sr as carbonate, followed by Fe(OH) 3 and BaCrO 4 scavenge precipitations (for Ba, Ra, Pb), were used in the CENTIS-DMR. Further purification was accomplished in this procedure by sequential Sr precipitations as chromate and finally carbonate.…”

“…Two laboratories using liquid scintillation counting as measurement method added liquid scintillation cocktail (Insta-Gel Plus) to the vials. [12] Although four laboratories measured the samples in LS counters, their measurement approach was completely different. Of the two laboratories using liquid scintillation counting, the IAEA applied a relative method with a calibration source of 90 Sr/ 90 Y made, following the same radiochemical procedure, from the same stable Sr carrier solution with a 90 Sr/ 90 Y standard of NIST added.…”

“…The MKEH reported an insignificant rounding error only. The IAEA, however, discovered later that the used calibration standard had an activity that was higher than stated in the certificate, which rendered the contribution of the IAEA to this comparison too low by about 10 % [14,12].…”

In 2009, the CCRI approved a supplementary comparison to be organized by the IRMM as pilot laboratory for the activity concentrations of 137 Cs, 90 Sr and 40 K in a matrix material of dried bilberries. The organization of this comparison and the material and measurement methods used are described. The supplementary comparison reference value (SCRV) for each of the three radionuclides are given together with the degrees of equivalence of each participating laboratory with the SCRV for the specific radionuclide. The results of this supplementary comparison allow the participating NMIs/designated institutes to declare calibration and measurement capabilities (CMCs) for the given radionuclides in a similar type of food matrix, an important aspect seen the relatively few supplementary comparisons for activity in matrix materials organized so far.
