Tugay A. Effect of Chronic Exposure on Soil Micromycetes of Chernobyl Exclusion Zone

Dissertation for obtaining a scientific degree of Candidate of Biological Sciences under specialization 03.00.01 Radiobiology. Taras Shevchenko National University of Kyiv, the Ministry of Education and Science of Ukraine, Kyiv, 2016. The dissertation is dedicated to researching remote effects of chronic exposure on post-radiation generations of micromycetes, which were obtained in model system. This model system imitated the levels of soil contamination of Chernobyl Exclusion Zone. It was shown that chronic radiation exposure in doses up to 18 Gy (within 3 months) had no influence on the survival of micromycetes, and these doses are small for micromycetes. It was demonstrated that post-radiation generations of control strains had increased radial growth and post-radiation generations with radioadaptive properties had increased the activity of antioxidant enzymes.
