The article presenting various-scale radiogeochemical investigations of the Kola Peninsula landscapes. Materials of long-term field works are used. Geochemical landscapes in the areas of nuclear industry influence have been studied in details. A series of landscape-geochemical maps was made at local (1:50000) and regional (1:2000000) scales, and the radioecological conditions were determined in the investigation area. The aim of the study was to determine in detail the migration and accumulation of technical radionuclides using 137Cs as an example in the Kola Peninsula. Large-scale landscape geochemical mapping plays an important role in studying the distribution of radionuclides. The aims of this study included the following tasks:- determination of factors and conditions, which facilitate migration and accumulation of technical radionuclides in the north-western part of the Kola Peninsula; — development of a series of landscape-geochemical maps at various scales for the study area;- development of an integrated geo-information database on 137Cs occurrence within study area. Landscapes have been identified according to the soil’s physical and chemical properties, vegetation characteristics, natural moisture conditions, groundwater level, the mineralogical composition of soil and underlying rocks, the presence or absence of anthropogenic impact. This approach has allowed the conditions of migration and accumulation of radionuclide sin the north-west of the Kola Peninsula to be revealed, and assisted in the understanding of migration and accumulation conditions of 137Cs.
