Did You Know a Tiny Core of plutonium Killed 2 Scientists? The “Demon Core” was a 6.2-kg plutonium sphere used to study nuclear criticality. During two separate experiments, scientists accidentally pushed the core into a supercritical state. Invisible radiation bursts occurred within seconds. Physicists Harry Daghlian and Louis Slotin were fatally exposed and later died from acute radiation sickness. After these accidents, hands-on criticality testing was permanently banned. #DemonCore,#LosAlamo
