ABSTRACT

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.
