Explosion - Atomic

The following overview summarizes the scientific principles, historical context, and immediate physical effects of an atomic explosion.

An atomic (fission) explosion occurs when the nuclei of heavy, unstable atoms—typically or Plutonium-239 —are split into smaller parts. This process, known as nuclear fission , releases a massive amount of energy due to the "nuclear difference," where nuclear reactions release roughly a million times more energy than chemical reactions. atomic explosion

: Using conventional high-explosive "lenses" to compress a plutonium core, increasing its density until it becomes supercritical (used in the "Fat Man" bomb and the Trinity test). Physical Effects of the Detonation : Using conventional high-explosive "lenses" to compress a

To trigger this explosion, the fissile material must reach a , where a self-sustaining chain reaction occurs. In modern designs, this is often achieved through: the fissile material must reach a
