Abstract

The scope of the paper is the current radioecological situation on the Kola Peninsula. Activity of existing enterprises in the region increases the potential danger of radioactive contamination. One of such enterprises is the ship reparation yard Nerpa specializing in the disposal of decommissioned nuclear submarines of the Russian Federation Navy since 1992. The aim of the study is to determine the degree of Nerpa influence on the environment by investigation of spatial distribution of ¹³⁷Cs in the upper soil horizons and lichens as the most reliable indicator of radioactive contamination.
