8. The Chernobyl Disaster (1986)
On April 26, 1986, the Chernobyl Nuclear Power Plant in Ukraine experienced a catastrophic explosion in Reactor No. 4, releasing large amounts of radioactive material into the atmosphere. The immediate vicinity was evacuated, and a 19-mile-wide exclusion zone was established, affecting hundreds of thousands of residents. The disaster led to significant health crises, including an increase in thyroid cancers among children exposed to radiation. The event profoundly impacted global views on nuclear safety and energy policies (nationalgeographic.com).
