Аннотация The large-scale nuclear accident took place at the production association “Mayak” in the Southern Urals in 1957. About 74 PBq of radioactive substances were released into the atmosphere, which resulted in the contamination of a vast area – East-Ural radioactive trace (EURT). The results of our study have shown that the density of contamination of 90Sr and 137Cs in the frontal part of the EURT are 6700-15000 and 200-400 kBq/m2, respectively. The total deposition for 90Sr within the East-Ural Radioactive State Reserve was 428.2 (286.4-643.4) TBq, for 137Cs – 15.1 (10.2-22.4) TBq, for 239,240Pu – 1.175 (0.623-2.242) TBq.
