A nuclear bunker is a fortified structure designed to protect people from the effects of a nuclear explosion and its aftermath. These bunkers are built to withstand blasts, radiation, and other dangers associated with nuclear fallout. They often include essential supplies, such as food, water, and medical kits, to support occupants during an extended stay. Typically constructed underground or in remote locations, nuclear bunkers can vary in size and complexity. Some are designed for individual families, while others can accommodate large groups or military personnel. The concept of nuclear bunkers gained prominence during the Cold War, reflecting concerns about potential nuclear conflict between nations, particularly the United States and Soviet Union.
