The concern about the environmental contamination by 241Am is caused by the fact, that its half-life period is longer and its mobility is much higher than that of parent plutonium. That is why in soils and sediments the specific activity of the radionuclide increases over time. The alpha-decay energy of 241Am and the relatively short lifetime of the isotope create high specific radioactivity and thermal yield. In bottom sediments, the ratio of 241Am to 241Pu increases every year. All these factors result in a high...

The sea coasts and estuaries are especially exposed to the oil pollution harmful influence as they frequently suffer from oil spills relating to the tanker accidents, port and off-shore activities. The objective of the present research is to examine the rates of spilled fuel oil natural destruction on geographically different seacoasts and to assess their self-cleaning capacity. For this purpose, a number of contaminated sectors of the Atlantic coasts of France and Spain (areas of пїЅErikaпїЅ and пїЅPrestigeпїЅ ta...
