Atomic bomb explosion. Mushroom cloud produced by the detonation of XX-12 Grable,a 15-kiloton nuclear shell,on 25 May 1953. This was part of Operation Upshot-Knothole at the Nevada Proving Grounds,USA. XX-12 Grable was fired from a 280mm artillery gun,the only time a nuclear artillery shell was ever fired. Atomic or nuclear bombs work by releasing energy from the nucleus of atoms. Fission bombs contain enriched uranium or plutonium. When an atom absorbs a neutron,it splits into smaller atoms,releasing energy (in the form of heat and radiation) and more neutrons,which propagate a chain reaction | |
