Abstract

Due to the importance of water in human life, its quality must be strictly controlled; so simple and reliable analytical methods must be available. For this purpose a rapid procedure for the determination of uranium isotopes in natural water samples with elevated salinity was adopted. It was tested in 16 water samples from Upper and Lower Silesia Regions in Poland. Water samples had salinity in a range of 290-26,925 mg l- 1. In water samples the concentrations of 234U and 238U ranged from 2.07 to 52.08 mBq l- 1 and from 2.18 to 43.38 mBq l- 1 respectively, while 235U level was below MDA (0.7 mBq l- 1). The isotopic ratio of 234U/238U varies in the range from 0.949 to 3.344 in all investigated waters which means that there is usually no radioactive equilibrium between the parent nuclide 238U and its daughter product 234U. These results do not show a correlation between total dissolved solids (TDS) values and concentration of dissolved uranium isotopes. Committed effective dose for adults due to uranium intake as a result of drinking water usage was in range of 0.15-3.29 μSv y- 1 with an average value of 1.09 μSv y- 1 far below the 100 μSv y- 1 WHO recommendation.
