- Аннотация: The influence of increased background radiation on the formation of magnetic nanoparticles of iron oxide (magnetite – Fe3O4 and maghemite – γ- Fe2O3) in the dominant plant species of Absheron Peninsular has been investigated by EPR method. It was shown that the intensity of a broad EPR signal, characterizing the magnetic nanoparticles of iron oxide, registered in dried leaves of studied plants, collected in various times of the year noticeably increases with increasing radiation background. Also in two investigating species of plants, it has been shown that the intensity of the broad EPR signal of seeds has been much lower than in their leaves. Such behavior has been observed with control plants, and also plants growing on polluted radionuclide soils (55 and 130 mR/hour). The elemental composition, radionuclide composition and specific activity of radionuclides in the studied plants have been determined. www.biosciencejournals.com
