This study presents the first comprehensive examination of 137Cs behavior in northern taiga ecosystems Kola Peninsula, a previously understudied region regarding radionuclide mobility. The background radioactive contamination these stems from global fallout and differs more extensively studied contaminated areas. Twelve monitoring sites at varying distances nuclear power plant were established to assess accumulation dominant species across three forest tiers. Gamma-spectrometric measurements revealed high mobility with specific activity ranging within 4.7-34.5 Bq/kg trees, 8.4-164.8 shrubs, 15.0-94.5 mosses. Notably, Ericaceae family plants demonstrated highest capacity. concentrations significantly higher site (30 km plant) than sanitary protection zone, indicating no detectable influence facility. Strong correlations (up |rs| = 0.93) between bioaccumulation indicators soil properties found-particularly potassium content, exchangeable cation concentration, organic matter content-suggesting that characteristics primarily determine These findings highlight potential risk movement through food chains ecosystems, coefficients exceeding those central Russian landscapes being comparable Scandinavian ecosystems.
