Chernobyl Disaster Response and Consequences

The Chernobyl disaster of April 1986 was a catastrophic nuclear accident. It began with a flawed safety test at reactor 4, leading to an explosion and massive radiation release. The immediate response was hampered by misinformation and denial. Evacuations were delayed, and the global community was alerted by radiation detected in Sweden. The disaster had long-term health and environmental impacts, leading to a reevaluation of nuclear safety worldwide.
