Chernobyl

Chernobyl was a disastrous event in history where there was a nuclear meltdown that made a nuclear wasteland in Ukraine. Chernobyl was a nuclear power plant that was running routine tests when it all went horribly wrong. When the workers at the nuclear power plant shut down reactor 4 in an emergency situation test, there was a sudden spike in power causing the nuclear rods to heat up and cause the water coolers to turn to steam and explode from the pressure. The explosion revealed the graphite moderator to air which in turn reacted and exploded sending fire and radioactive material into the air. The immediate explosion killed 31 workers but the nuclear fallout caused many more problems that are still apparent today. The death toll due to radiation in 2008 was 64 people. The majority of the radiation deaths were from cleanup workers or other workers who were on site when the explosion happen. Other deaths include children who got cancer from nearby towns and cities along with others. The explosion did not just affect people, it affected the environment as well. Groundwater in some places became to dangerous to drink. A forest directly downwind from Chernobyl turned red then died. A massive reservoir, Dneiper, became dangerous to drink, although it became safe again shortly after. Chernobyl was classified as a class 7 disaster, the highest class of nuclear disaster. The area affected by the disaster is unparalleled by any other disaster having an effect on 162,000 square miles around the plant. The response to this disaster was way under par. After the explosion, no one alerted the nearby city Pripyap and several people fell ill and got radiation sickness. It wasn't until a day later did they announce that there had been an explosion and that people should evacuate. The only announcement that was made to the world was a twenty second broadcast that hardly told anyone what had happened. The announcement was as following: 

There has been an accident at the Chernobyl Nuclear Power Plant. One of the nuclear reactors was damaged. The effects of the accident are being remedied. Assistance has been provided for any affected people. An investigative commission has been set up.
