Sažetak
Laboratory for Measurements of Low-level Radioactivities, Ruđer Bošković Institute (RBI) from Zagreb, Croatia, and Laboratory for Nuclear Physics, Department of Physics of the University of Novi Sad (DP-UNS), Serbia, have performed inter-laboratory comparisons of measurements of tritium (3H) and radiocarbon (14C) activities in various environmental samples. Both laboratories have the same type of detector, ultra low-level liquid scintillation counter (LSC) Quantulus 1220, but use different sample preparation techniques. Both methods of 3H measurements, the direct measurement at DP-UNS and electrolytic enrichment at RBI, give comparable results, with better precision and lower MDA of the enrichment method. Direct comparison of methods for 14C measurement was not possible because in the DP-UNS sample preparation method the exact proportion of carbon in the sample is not known and requires additional measurements.
