چکیده
The article presents the results of a study of soils and bottom sediments of lakes in the area of Monchegorsk city. The purpose of the work is to identify patterns of distribution of natural and man-made radionuclides in urban soils and bottom sediments of lakes in Monchegorsk city. The specific activity values of radionuclides in urban soil samples were as follows: for technogenic 137Cs, up to 31.3 Bq/kg; in soils in the zone of influence of the plant (in subflare areas), up to 63.4 Bq/kg. For natural radionuclides in urban soils, the values were as follows: 226Ra – up to 14.2 Bq/kg; in soils in the zone of influence of the plant (in sub-flare areas) – up to 21.6 Bq/kg; 232Th in urban soils – up to 1. The concentration of 8.3 Bq/kg was observed in soils in the zone of influence of the plant (in sub-flare areas), while the concentration of 17 Bq/kg was observed in soils in the same area. The concentration of 498 Bq/kg was observed in urban soils for 40K, while the concentration of 317 Bq/kg was observed in sub-flare areas. In bottom sediments of lakes, the concentration of technogenic 137Cs was found to be up to 45.8 Bq/kg, while the concentration of natural radionuclides, including 226Ra (up to 62.6 Bq/kg), 232Th (11 Bq/kg), and 40K (268 Bq/kg), was also determined.
