The Troubling Story of the Nuclear Demon Core
Slotin accidentally began a fission reaction, which released a burst of hard radiation. Slotin was rushed to the hospital, and died nine days later, the victim of the second criticality accident in history, following the death of Harry Daghlian, who had been exposed to radiation by the same core that killed Slotin.
