The Demon Core: The Deadly Legacy of Nuclear Experimentation

🔬The Demon Core was a plutonium sphere used for criticality experiments.

⚛️Criticality occurs when a nuclear core goes prompt critical, releasing a chain reaction of exponentially more atoms.

☢️The accidents with the Demon Core resulted in severe radiation poisoning and ultimately death for the scientists involved.

🔴The prompt criticality accidents of the Demon Core highlighted the risks and dangers of nuclear experimentation.

🌍These accidents led to increased safety measures and awareness surrounding the handling of nuclear materials.

What was the purpose of the Demon Core?

—The Demon Core was used for criticality experiments to study the conditions required for a nuclear core to go critical.

How did the accidents happen?

—The accidents occurred when the neutron reflecting material around the core was improperly handled or positioned, leading to prompt criticality.

What were the effects of the accidents?

—The accidents resulted in severe radiation poisoning for the scientists involved, leading to their deaths.

What lessons were learned from these accidents?

—These accidents highlighted the importance of strict safety protocols and procedures when working with nuclear materials.

How have these accidents impacted nuclear experimentation?

—The accidents led to increased safety measures and regulations to prevent similar incidents from occurring in the future.

00:03In 1946, a plutonium core known as the Demon Core was scheduled for detonation but was harmlessly melted down instead.

04:23During criticality experiments, the Demon Core went prompt critical, releasing a wave of radiation.

10:22Lewis Slaughten conducted a screwdriver experiment with the Demon Core, resulting in prompt criticality and his exposure to a fatal dose of radiation.
