Sažetak
Measurement of low-level tritium activities in natural/non-polluted waters, e.g. in precipitation and groundwater, requires special techniques for water pretreatment and detection of low-level radioactivity. Two methods for low-level tritium measurement have been developed in Zagreb Radiocarbon and Tritium Laboratory: gas proportional counting (GPC) and liquid scintillation counting (LSC). Method of electrolytic enrichment of water samples with tritium followed by measurement by LSC Quantulus 1220 has been developed in 2008. Here we present the comparison of the two measurement techniques. Our Laboratory participated in the intercomparison study organized by the IAEA, TRIC2008. The data evaluation of six samples revealed that all results measured by LSC are accepted, as well as four GPC results, while two GPC results of samples with low tritium activity (<2 TU) are in the warning level.
