atomic bomb(redirected from atomic bomb irradiation)
Also found in: Thesaurus, Medical, Encyclopedia.
An explosive weapon of great destructive power derived from the rapid release of energy in the fission of heavy atomic nuclei, especially of uranium-235 or plutonium-239. Also called A-bomb, atom bomb, fission bomb.
1. (Atomic Physics) a type of bomb in which the energy is provided by nuclear fission. Uranium-235 and plutonium-239 are the isotopes most commonly used in atomic bombs. Also called: A-bomb or fission bomb Compare fusion bomb
2. (Firearms, Gunnery, Ordnance & Artillery) a type of bomb in which the energy is provided by nuclear fission. Uranium-235 and plutonium-239 are the isotopes most commonly used in atomic bombs. Also called: A-bomb or fission bomb Compare fusion bomb
1. a bomb whose potency is derived from nuclear fission of atoms of fissionable material with the consequent conversion of part of their mass into energy.
2. a bomb whose explosive force comes from a chain reaction based on nuclear fission in U-235 or plutonium.Also called A-bomb, atom bomb.
A very destructive bomb that derives its explosive power from the fission of atomic nuclei, usually plutonium or uranium 235 (an isotope of uranium). Also called atom bomb.
