Sažetak
The RadiÖko Ltd. radioanalytical laboratory and Laboratory for low-level radioactivities of the Ruđer Bošković Institute (RBI) performed an interlaboratory comparison for the determination of H-3 and C-14 activities in water samples. Three samples were measured for H-3, two for C-14 activity. Each laboratory applied their own sample preparation techniques for H-3 determination and the activities were measured by LSC Quantulus 1220. At the RBI the low H-3 activity sample A was measured by both direct and electrolytic enrichment method. For the determination of the radiocarbon activity the Zagreb laboratory used AMS technique, whilst RadiÖko used an own developed sample oxizer followed by LSC measurement using a Quantulus LSC. It is interesting to note that all three H-3 results of the RadiÖko group are lower than those obtained at RBI. The results of the two radiocarbon measurements reveal that in the case of sample D the measurement results of the laboratories lie close to each other. Sample E had too high activity to be determined by AMS technique, this way it is not possible to compare the results. In all the successfully conducted cases it is apparent that the differences are well below the 10% satisfactory range.
