Abstract

The content and profile distribution of ¹³⁷Cs 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 ¹³⁷Cs in the root-inhabited layer (0–30 cm) in the studied soils was significantly lower than the established control level of 37 000 Bq/m² and amounts to 530–2459 Bq/m². A significant part of ¹³⁷Cs (60 to 90%) was concentrated in mineral horizons. It has been shown that the pollution density of ¹³⁷Cs in the observation zone of a nuclear power plant was mainly due to global fallout. The greatest influence on ¹³⁷Cs accumulation in the studied soils was exerted by the organic matter reserve.

可乐核电站地区Podzols中137 Cs的含量和分布

摘要

分析了可乐核电厂附近越桔-地衣和绿地衣-越桔松林下铁-矮小矮土和浅土式青豆（Albic Podzols）中¹³⁷ Cs的含量和分布。被研究土壤中根部居住层（0–30 cm）中¹³⁷ Cs的污染密度（储量）显着低于既定的控制水平37 000 Bq / m ²，达到530–2459 Bq / m ²。¹³⁷ Cs的很大一部分（60％至90％）集中在矿层中。研究表明，核电厂观测区内¹³⁷ Cs的污染密度主要是由于全球尘埃落差所致。影响最大¹³⁷ Cs在土壤中的积累是由有机质储量引起的。
