The most comprehensive review in the world literature of medical, environmental and biological research on the consequences of the Chernobyl disaster for the population and nature In Part I (authors A. In. Apples and B. B. Nesterenko) considered the geographical and environmental features of pollution of territories, in part II (A. In. Yablokov) considered methodological approaches to clarifying the impact of Chernobyl pollution, in part III (A. In. Apples and N. E. Preobrazhenskaya) reviewed data on overall morbidity and mortality, features of the incidence of diseases of various organs and systems in radioactively contaminated areas, in part IV (A. In. Apples, A. In. Nesterenko, N. E. Preobrazhenskaya) - consequences for nature, and in part V (B. B. Nesterenko, A. In. Nesterenko) - ways to minimize the consequences of the Catastrophe for the affected population . The opinion about the insignificance of the consequences of the Catastrophe does not correspond to the facts that show that in terms of the coverage of the territories (the entire Northern Hemisphere), in terms of the number of victims (hundreds of thousands) and in terms of the duration (century) the Chernobyl disaster is the largest man-made disaster in the history of mankind.
