Název v původním jazyce
Radium isotopes in river sediments of Czech Republic
Popis výsledku v původním jazyce
In the Czech Republic, river bottom sediments have been systematically monitored since 1999. In the paper, their radioactive contamination due to uranium mining and milling is assessed. The sediments samples were analyzed by gamma spectrometry. Especially the radium226 and radium-228 activities were further evaluated. The highest values of the radium-226 activities were found at river profiles where the uranium industry impact was obvious. It turned out that the radium226 and radium228 activities ratiois more convenient to assess the level of radium226 contamination than only the radium226 activity itself. Based on this hypothesis, the sediment classification scheme for uranium industry contamination was suggested. The natural background activities ofradium226 and radium228 in the Czech Republic were also evaluated. The case of radium-226 contamination due to the uranium industry was studied in details at the Ploučnice River.
