Twenty-one laboratories pre-concentrated three of 10 L samples by ve di erent pre-concentration methods (Prussian-blue-impregnated lter cartridges, coprecipitation with ammonium phosphomolybdate, evaporation, solid-phase extraction disks, and ion-exchange resin columns), and activity of radiocesium was measured. The z-scores for all of the 137Cs results were within ± 2, indicating that the methods were a good degree of precision. The relative standard deviations (RSDs) indicating the reproducibility among di erent laboratories were larger than the RSDs indicating the repeatability in each separate laboratory.}, pages = {477--485}, title = {Repeatability and reproducibility of measurements of low dissolved radiocesium concentrations in freshwater using different pre‑concentration methods}, volume = {322}, year = {2019} }
