Summary:The newly established Ionizing Radiation Metrology Laboratory of the National Metrology Institute (FTMC) in Lithuania organized four comparisons in the field of low-level radioactivity measurements in water. For gamma-ray emitters, the activity concentration in the samples was in the range 1–25Bq/kg, while for tritium it was around 2Bq/g. The assigned values of all comparisons were traceable to the primary standards of the Czech Metrology Institute (CMI). •Variant comparisons to check performance of participants.•Capability of test laboratories to analyze low-level activity samples.•Challenge in detection of 109Cd.•Difficulties in calibration and uncertainty estimation for 3H.•Role of the national radionuclide activity standard laboratory.
