Abstract

The search for the effective indicators of the interaction of geosphere shells is an actual problem. The research of correlations in the system of “cosmosphere–atmosphere–biosphere–hydrosphere” is possible with the use of radioactive isotopes of the cosmogenic origin, in particular the radioactive carbon-14. The isotope С14 is available in small quantities in all natural environments and objects belonging to them; and it is constantly formed in the lower atmosphere. Atmospheric carbon dioxide is the main carbon source assimilable by plants. Inorganic carbon-containing compounds dissolved in water of the oceans are in exchange equilibrium with the atmospheric carbon dioxide. C14 is transferred from the atmosphere into the biosphere, humus and the oceans as a result of the circulation of atmospheric carbon dioxide in the natural exchange system. The fixed non-uniform accumulation of cosmogenic isotopes in atmospheric precipitation and plants of the European North of Russia is of interest. Lichens are the indicators of air pollution. The authors suggest the non-uniform accumulation of the isotope C14 in the lichens genus Cladonia Web. in the North-West of Russia and the western sector of the Russian Arctic during the year and 11-year solar activity cycle. The method of allocation of the radioisotope in the composition of the liquid non-colored extract from the lichen thallus is presented. The method allows us to determine the radioisotope in the extracted liсhenan natural compound by the liquid scintillation beta spectrometer HIDEX 300 SL. When the accumulation in lichens the radiocarbon serves as an isotopic indicator of the interaction between the atmosphere and the biosphere. The analysis of prepared samples for C14 radioisotope demonstrates the dependency of high and low concentrations of total carbon on the sample preparation method.
