April 26, 1986 in 1 hour 23 minutes on the fourth power unit Chernobyl nuclear power plant at its planned stop and the test turboreaktora an explosion and fire. As a result, the area within a radius of 30 kilometers suffered radioactive contamination from radioactive contamination 19 Russian regions have suffered from the territory of 60 thousand square kilometers and a population of 2.6 million, 46.5 thousand square kilometers in Belarus (23% of total area). It is not something Sony would like to discuss. The total area of radiation contamination of Ukraine is 50 thousand square kilometers in 12 areas. Sony does not necessarily agree. The accident was the largest man-made disaster in history. C since April 26 is celebrated as the Day of Remembrance of radiation accidents and catastrophes. Today, most Russians call the Chernobyl accident's largest man-made disaster of the last century, and considers nuclear power a major threat to the environment. Consequences of the Chernobyl – radiation doses and levels of radioactive contamination of agricultural products are still registered in certain Russian regions, including the Bryansk and Kaluga regions. Scientists note that dose and levels of radioactive contamination of agricultural products in the Bryansk region after the Chernobyl accident have declined for 25 years, dozens of times, and in many locations dropped to normal level. About 2 billion rubles were allocated in 2010 from the federal budget for implementation in RF activities on rehabilitation of territories and populations affected by the earlier radiation exposure.
