Sažetak
Major elements concentrations (Na, K, Ca, Mg) and the activity concentrations of 226, 228Ra, 234, 238U, 210Po, 210Pb, 40K and 137Cs in northern and eastern Croatian thermal and mineral waters, collected directly from springs (or wells), are presented herein with total effective doses assessed for those waters that are considered as drinking “cures” and are available for consumption. The methods used for radionuclide determination included alpha- particle spectrometry, gas-proportional counting and gamma-ray spectrometry, while the major element composition was determined by ICP-MS. The activity concentrations of all of the radionuclides were found to be below the guidance levels set by the WHO and EC Directive, with the exception of one water sample that measured 0.26 Bq L–1 of 228Ra. The effective ingestion dose assessment for the consumption of the so-called water “cures” during one, two or four weeks’ time period throughout one year was well below the recommended 0.1 mSv for drinking water.
