The gross α–β activities of 226Ra, 232Th and 40K in underground water samples were determined and γ spectroscopy measurements made as well. The gross α–β concentrations were measured using a low background gasless automatic α–β counting system calibrated with 241Am and 90Sr standards for α and β, respectively, while γ analyses were carried out using γ spectrometry system coupled to a NaI (TI) detector...
