In 2016, the Chernobyl nuclear accident, which was shocked by the world, has been 30 years away. Thirty years later, once again mentioned this place name, many people have not known how terrible things happened here. Chernobyl - a prefecture-level city in Kiev, Ukraine. The city of Pripyat is not far from the Kiev reservoir. It is located to the north of Kiev, the capital of Ukraine, and is 115 km from the road to Kiev. The name Chernobyl was first mentioned in 1193, when it was under the control of the Poles. On April 26, 1986, the No. 4 reactor at the Chernobyl nuclear power plant exploded, which became the biggest disaster in the history of human beings' peaceful use of nuclear energy. This is the most serious nuclear accident in history. The radiated dust leaked out with the atmosphere to the western part of the Soviet Union, Eastern Europe, Scandinavia in the Nordic, the British Isles and even parts of North America, including Ukraine. Belarus, and western Russia are the most polluted. Due to wind direction, it is estimated that about 60% of radioactive material falls in Belarus. Today's Chernobyl is a deadly nightmare. Although the radiation dose is not as high as it was, the genetic mutation after the accident is still happening. The villagers in the village of Narodic said that the offspring of their livestock were either completely blind or the eyes were as big as watermelon. The variation in poultry is surprising, with plant mutations reaching almost 100%.
