Radiometric Studies on Carbonated Natural Mineral Waters from the Northern Part of Romania

Abstract:

As the access to a safe drinking water is essential to human health, a radiometric studywas conducted on a natural mineral carbonated water, located in the northern part of Romania, as a subject to international rules. Activity concentrations of gross alpha and gross beta, of the radionuclides natural decay chains238U, 232Th and 40K were determined, as well as the associate effective dose for these radionuclides. It was found that the low permeability of the aquifer allows a reduced infiltration of the rain water, seasonal influence showing good chemical stability, oscillating around less than 10%. The results obtained for the effective doses calculated for an adult in Romania, derived from the intake of naturally occurring radionuclides in water varies between: 1.24-2.08(µSv/yr) for 40K; 0.90-3.45 for 238U; 1.00-7.21(µSv/yr) for 232Th and 11.24-46.00 (µSv/yr) for 226Ra.The assessment on natural mineral waters from Bucovina region updates the data on the activity concentrations and effective doses due to intake of natural radionuclides for Romania. The obtained values are below the WHO and UNSCEAR recommended reference levels. Keywords: mineral water, ground water, radioactivity, gross-a and gross-g, effective dose
