En la naturaleza siempre han estado presentes las radiaciones ionizantes, por lo que el hombre siempre ha convivido con ellas, si bien es cierto que estas también pueden tener un origen artificial. El Comité Científico de la ONU para el Estudio de los Efectos de Radiaciones Atómicas (UNSCEAR), estima un valor promedio de 2,4mSv/año para la...

The distribution and behaviour of Polonium (210Po) in marine organisms has been and is now a subject of great interest because of their relatively high concentrations in comparison with those in terrestrial organisms and its relatively high weight in the doses received by humans via ingestion. However, depending ...

This paper presents the levels and distribution of 210Po in different compartments of a coastal lagoon on the east coast of Uruguay (South America). Activity concentrations of 210Po have been obtained in different matrices, such as water, superficial sediments, clams (Diplodon sp.), freshwaters snails (Pomacea sp.), zooplankton, and fishes...

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...
