title: [Current radiation status of the ecosystem of the Lake Bolshoi Igish situated along the axial part of the East-Urals radioactive trace].
abstract: Data on the current radioecological status of lake Bolshoi Igish in the Middle Ural are presented in the paper. The lake is situated on the central axis of the East-Urals radioactive trace which was formed as a result of the 1957 nuclear accident at the Mayak Production Association. The distribution of 90Sr and 137Cs in the major components of the water basin is shown. Seasonal dynamics of the specific activity of radionuclides in water and in bottom deposits has been investigated. The current community of the higher water plant species has been studied. The paper discusses the concentration of 90Sr and 137Cs in the macrophyts of lake Bolshoi Igish depending on their species.
