Contents and Distribution of 137Cs in Podzols in the Area of the Kola Nuclear Power Plant

The content and profile distribution of 137 Cs in iron-illuvial dwarf and shallow-podzolic podzols (Albic Podzols) under bilberry-lichen and green-lichen-bilberry pine forests in the located near the Kola Nuclear Power Plant have been analyzed. The pollution density (reserve) of 137 Cs in the root-i...

Description
Summary:The content and profile distribution of 137 Cs in iron-illuvial dwarf and shallow-podzolic podzols (Albic Podzols) under bilberry-lichen and green-lichen-bilberry pine forests in the located near the Kola Nuclear Power Plant have been analyzed. The pollution density (reserve) of 137 Cs in the root-inhabited layer (0–30 cm) in the studied soils was significantly lower than the established control level of 37 000 Bq/m 2 and amounts to 530–2459 Bq/m 2 . A significant part of 137 Cs (60 to 90%) was concentrated in mineral horizons. It has been shown that the pollution density of 137 Cs in the observation zone of a nuclear power plant was mainly due to global fallout. The greatest influence on 137 Cs accumulation in the studied soils was exerted by the organic matter reserve.
