Water samples were collected from 124 springs in Slovenia and analysed for tritium (3H). Tritium was enriched electrolytically and its concentration determined by liquid scintillation analysis. Tritium concentrations ranged from 325 to ca. 3000 Bq m–3, with a geometric mean of 1223 Bq m–3 and geometric standard deviation of 1.6. Although tritium concentrations in springs are generally low, they proved to be useful in qualitative assessment of recent recharge.
