| الوصف: |
The main aim of this work was to determine the levels of multiple natural radionuclides in an aquatic system(Moulouya river, Morocco) impacted by multiple abandoned Zinc and Lead mines.238U,234U,232Th,230Th and210Po were determined by alpha-particle spectrometry in water and sediment samples collected along the riverand in samples from three pit lakes of abandoned mines, located in the Upper Moulouya catchment area.The results enabled the analysis of the different levels of impact of former mining activities, depending on thenatural radionuclides. While the activity concentration of U-isotopes in Moulouya river water was slightlyelevated in the vicinity of abandoned mine wastes, other natural radionuclides (Th-isotopes and210Po) levelswere typical of a natural environment. This fact is clearly reflected in the magnitude and range observed in thedistribution coefficients for the different radionuclides analyzed. |
