Mobility and transport of cesium and strontium in soil erosion by water

Abstract

It was apparent that the cesium migrates horizontally in greater proportions than the strontium that pooly fixes on the particles and infiltrates into the first centimeter of the soil. One parameter to take into account would appear to be the initial humidity of the soil. The sedimentary crust favours the exportation of cesium and strontium by preventing its infiltration, while at the same time trapping part of the contamination on its immobile particles. In the case of wet discharge, the contamination of cesium tends to disperse. It is now necessary to extend the domain of study of our factors for completing results. Dry periods in structural history and organic contents appeared to be most important.

Leaching of strontium from Albic Retisol limed with Sr-containing industrial waste

“…Strontium is an active water migrant (Claval et al, 2002;Dubchak, 2018) and highly reactive alkaline metal . It migrates especially vigorously in humid landscapes with Sr ahead of Ca in terms of the intensity of runoff into the ocean.…”

“…In addition, surface soil layer containing higher amount of organic matter are prone to water erosion. This poses a risk of secondary contamination driven by horizontal migration contributing to the spread of Sr through the agricultural catchment area (Claval et al, 2002).…”
