The Demon Core: Deadly Nuclear Accident

The demon core was a small plutonium sphere used in early nuclear research. It stayed close to a chain reaction, so even a tiny change could trigger a burst of radiation. In 1945, Harry Daghlian caused a critical reaction by mistake and died weeks later. In 1946, Louis Slotin repeated a similar test, a tool slipped, and he died within days. After these incidents, scientists stopped manual experiments and introduced strict safety systems. This core showed how fast small errors in nuclear work tur
