Key Environmental Engineering Strategies

Te duże fizykale intervention to date has been thee removal of topsoil, primaryly from agricultural land, residential areas, and roadsides, and d roadsides. In practice, this mean stripping thee upper 5 cm of soil - thee depth where over 80% of radiocesium had accumulated - and reveting it with clean material or tilled subsoil.

Environmental developments are now focused on volume reduction technologies to shrink thee footprint of this stold soil. Thermal treatment, such as spalarne of organic- rich fractions andd vitrification of residual ash, can reduce mass more than 90% while immobilizing cesiume in a leach- resistant glass matrix.
