Radionuclides in the Environment, Radioecology
Invited
Under articles 35 and 36 of the European Atomic Energy Community (EURATOM) Treaty, the Member States of the European Union are obliged to inform the European Commission on a regular basis of the radioactivity levels in their environment. The Council directive 2013/51/EURATOM of 22 October 2013 laying down requirements for the protection of the health of the general public with regard to...

In order to facilitate the selective sequestration of important radionuclides and contaminants, a surface attached ligand, (3-Aminopropyl)triethoxysilane (APTES) has been attached to 2 types of silica with very different surface...

Waste waters that contain radioactive metal ions like Sr(II) or Am(III) are dangerous for the environment. There are several methods to remove them from waste water using ion exchange resins, chemical precipitation or reverse osmosis. Very often sorption, precipitation or complexation is combined with ultrafiltration in one hybrid process of enhanced ultrafiltration. Small ions bound by...

The concentrations of 210Pb, 210Bi and 210Po were measured from February 2010 to May 2010 and from May 2011 to April 2012. The seasonal change of 210Po/210Pb and 210Bi/210Pb activity ratios indicate on independent fluctuations of tropospheric 210Pb and its decay products, particularly 210Po. A simple calculation method for the estimation of the excess of 210Po, in relation to its activity...

Uranium and plutonium extraction from spent nuclear fuel leads to formation of high-level waste (HLW) with complex composition. Actinides (An) from HLW due to their long half-lives (103-106 years) are the most dangerous elements for biosphere in long-term perspective. To enhance the effectiveness of waste handling it is expedient to extract from HLW An and rare earth elements (REE) in separate...
