radioactive cesium remediation

Novel two-step process for remediation of Cs

Radioactive cesium (137 Cs) is apriority radionuclide and a major concern in soil systems because it is specifically stabilized in clay minerals , . Since the Fukushima nuclear accident in March 2011, a substantial amount of Cs was distributed over a wide area and has remained at the top-soil (0–5 cm) because of its strong affinity for clay ...
