Radionuclides in the Environment, Radioecology

Verbal

The dominant development in the radiometrics techniques has been the utilisation of large HPGe detectors in underground laboratories with anti-cosmic or anti-Compton shielding for the analysis of short and medium-lived radionuclides in the environment. They have included applications of high efficiency HPGe detectors (up to 200% relative efficiency to a 75 mm diameter, 75 mm long NaI(Tl)...

Radionuclides in the Environment, Radioecology

Verbal

Sorption–desorption behaviour of Cs, Pu and Am in the system was studied using data obtained from different sampling campaigns in the Baltic Sea and the Curonian Lagoon in 1999-2009 as well as from short- and long-term kinetic tracer experiments using natural sea or river water and bottom sediments collected in the Curonian Lagoon or the Baltic Sea. Sorption experiments were carried out with...

Radionuclides in the Environment, Radioecology

Verbal

During the International Scientific Cruise to Adriatic and Ionian Seas organised by the International Atomic Energy Agency (IAEA), sediment and rock samples were collected at different locations. Sediments were sampled with grab corer at six locations in the middle and south Adriatic Sea. Rocks were collected on three islands (Palagruža, Brusnik, Jabuka) in the Adriatic Sea. In the samples,...

Radionuclides in the Environment, Radioecology

Verbal

One of the most important factors determining the radioecological situation in the terrestrial ecosystems is the radionuclide species in a soil medium. Radionuclide forms determine the processes of their entrance into the soil solutions, redistribution in soils, migration to the surface, ground and underground waters and spreading outside of the contaminated area. The present work is devoted...
