Chernobyl Disaster

My presentation was about a disaster that took place in Ukraine. It was the largest uncontrolled radioactive released into the environment, that was ever recorded for any civilian operation. The disaster was a unique event and the only accident in the history of commercial nuclear power, where radiation-related fatalities occurred. It was caused while the testing of the reactor number four. They were testing the reactor, to determine how long turbines would spin and supply power to the main circulating pumps, which in that moment a loss of the main electrical power supply occurred. The reactor was on an unstable condition when the people tried to shut it down, and the explosion happened. It caused an explosion and a melt down.That caused reactor number four to spew over 200 times the amount of radiation. The Chernobyl Disaster affected over seven million people, including the areas of Belarus, Russia, and Ukraine. The incident caused people to evacuate the location, and some never came back home. After the disaster, it caused people to become disabled, dead, or some even committed suicide. There were health issues such as the rise in thyroid cancer or any thyroid disease, immune system disorders, lung,heart, and blood problems, and finally learning problems for children. To solve that event, $400 million, U.S dollars, was put into that event, to improve the situation. 600,000- 800,000 firefighters and emergency workers were sent to help out from the Soviet Union to put out fires, bury radioactive equipment, shut down all Chernobyl reactors, and they also created a tomb to surround the radioactive material that collapsed from the reactor.
