摘要
This paper presents the results of radiometric measurements and the main physical-chemical parameters obtained on samples of natural mineral water commercially available. The water samples originate from the Bucovina region, which is located in the northern part of Romania. Gross alpha and beta activities were measured for screening purposes and for guidance to the competent authorities in determining whether the water can be used for human consumption. Activity concentrations of K-40, U-238, Th-232 and Ra-226 were also determined, as well as the associated effective dose. The mean effective doses for an adult member of the public in Romania derived from the intake of naturally occurring alpha or beta radionuclides (K-40, U-238, Th-232 and Ra-226) in natural water varies between: 0.66 and 2.17 (A mu Sv/year) for K-40; 1.12 and 1.71 (A mu Sv/year) for U-238; 1.79 and 3.95 (A mu Sv/year) for Th-232 and 5.75 and 20.61 (A mu Sv/year) for Ra-226. This assessment on natural mineral water springs from the Bucovina region updates data on the activity concentrations and effective doses due to intake of natural radionuclides for Romania.
