Abstract
The environmental factors considered are: surface water, ground water, drinking water, soil, sediment and spontaneous vegetation. The analyses performed showed a low level of radioisotopes. The mean values recorded were: 4.22×10−3 Bq dm−3 for137Cs, 2.97×10−3 Bq dm−3 for90Sr, 14.9 Bq dm−3 for3H and 1.07 μg dm−3 for U, in the Danube waters. The γ-spectrometric analysies revealed lines corresponding to40K and the to the natural decay series of U and Th. There have been also identified the artificial radionuclides137Cs and60Co in sediment,95Zr and95Nb in the 1981 vegetation. All artificial isotopes resulted from atmospheric fallout.
