Speciation of radiocesium in atmospheric aerosol after the Chernobyl accident

Abstract

The aim of this analysis was to verify the hypothesis that physico-chemical forms of radiocesium in the fallout after the accident could depend on the transport conditions, including the distance of a sampling location from Chernobyl. From the results it is obvious that the prevailing form in all samples taken in the period of direct contamination was water-soluble radiocesium. It can be concluded from the presented results that physico-chemical forms of radiocesium in atmospheric aerosol and fallout after the nuclear power plant accident at Chernobyl as well as particulate size distribution can depend on the distance or the conditions of transport from a contamination source to a sampling location. The influence of the conditions of radiocesium transport could result in observed differences in the {sup 137}Cs penetration into soil profile in different locations and also in the found dependence on the resuspension factor for {sup 137}Cs on the level of its fallout in the period of NPP accident for different locations in Europe.
