摘要：
Data are presented concerning Sr-90 and Cs-137 concentrations in taxonomically different lichens and mosses, and concentrations of radionuclides in the moss-lichen cover of terrestrial communities studied in the Ural-Siberian Region. Radioactive contamination of lichens and mosses is determined by long-lived radionuclides arriving with global fallout from the atmosphere. The dynamics of Sr-90 and Cs-137 concentrations in moss-lichen communities is shown. The data obtained can be used for the general assessment of the radiological situation in the Ural-Siberian Region and for long-term radiation monitoring in the northern territories.
