Explanation:

The Chernobyl nuclear plant created the biggest disaster a nuclear plant has made since they have been used. This nuclear plant was int he territory of the former Soviet Union, while nowadays it is located in the territory of Ukraine. This nuclear plant was located in the northern part of what is now Ukraine, right next to the border with present day Belarus. On April 26, 1986, the reactor design flaws and the breaching of protocol during a simulated power outage safety test led to a disaster, with the nuclear plant starting to spread radiation around it. The few towns and villages nearby were immediately evacuated, but lot of people were exposed to such high radiation levels that they died very quickly or soon after. Because of the movement of the air masses and the open and relatively flat space all around the plant, the radiation was spread around big portion of Europe, having very bad effects on the human health, as well as the animals and plants that were affected by it. The area to this day still has very high levels of radiation and it is totally abandoned by humans, though the plants and animals have returned and repopulated, thriving in the absence of humans.
