Self-PR
Ph.D. in Chemistry from the Institute of Chemical Physics of Russian Academy of Science (1983) for studies in atmospheric chemistry and Doctor of Science degree in Radiobiology from the Institute of Agricultural Radiology (1998) for studies of radiocesium and radiostrontium behavior in the environment after the Chernobyl accident. My field of expertise is the environmental behavior of contaminants including accidentally released radionuclides. Currently, my research focuses on the Fukushima-derived radiocesium behavior in the soil-water environment and its comparison with Chernobyl and Mayak cases. After the Fukushima accident, my ambition was to do research in the Fukushima area to check how well we understand the basic mechanisms of radiocesium behavior in the environment. This was realized in 2013 when I started to work for the Institute of Environmental Radioactivity at Fukushima University. Performed researches in 2014-2016 demonstrated that our understanding of r-Cs speciation and migration processes adequately explains differences and similarities in the radionuclide's behavior in Fukushima, Chernobyl, and Mayak areas. Climate and geographical conditions for Fukushima Prefecture of Japan, Chernobyl's near-field zone, and Mayak area are obviously different. The landscapes and soils also differ significantly. Moreover, the speciation of radiocesium in all three releases was distinct. Comparative analyses have been carried out for r-Cs wash-off parameters and distribution coefficients, Kd, in rivers and surface runoff for the three contaminated areas. The r-Cs distribution coefficient in Fukushima rivers was 1-2 orders of magnitude higher than corresponding values for rivers and surface runoff of Chernobyl and Mayak areas. This is indicative of the higher ability of Fukushima soils and sediments to bind r-Cs. The normalized dissolved wash-off coefficients for Fukushima river watersheds are 1-2 orders of magnitude lower than those for Chernobyl and Mayak areas. The effective dispersion coefficients, however, in Fukushima soils were found to be relatively high as compared to Chernobyl and Mayak. In general, due to higher precipitation, higher temperatures, and higher biological activities in soils, self-purification of the environment and natural attenuation in Fukushima is essentially faster than in Chernobyl and Mayak areas.
