Ecological Systems and Devices Annotation << Back About influence of radioactive pollution of district to the chemical composition of atmospheric air Vedernikova A.P. Buzanovskii V.A. Samkharadze T.G. Vahitov A.R. Theoretical representations about possible influence of radioactive pollution of district to a chemical composition of atmospheric air are considered in the article. It is marked, that radioactive pollution of district, in particular by such long-living radioactive particles as cesium-137 with a half-life period of 30 years and strontium-90 with a half-life period of 28,5 years, is characterized by presence of photon radiation as γ-radiation and corpuscular radiation as a stream of electrons of β-radiation. Influence of γ- and β-radiations leads to excitation, ionization and dissociation of molecules of chemical compounds of atmospheric air. The excited molecules, splinters of the molecules, positively (negatively) charged ions and free electrons are formed in this case. The change of a chemical composition of atmospheric air as in a value of concentration of air components and as in a nomenclature of air components can be caused at the further transformations. Keywords: radioactive pollution; ionization radiation; radioactive particle; atmospheric air; air component; chemical composition. Contacts: E-mail: vab1960@rambler.ru Pp. 03-11.
