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, fission bomb Compare fusion bomb
A very destructive bomb that derives its explosive power from the fission of atomic nuclei. Atomic bombs usually have plutonium 239 or uranium 235 as their fissionable material. Also called atom bomb.
atomic bomb (A-bomb)
A nuclear weapon whose enormous explosive power results from the sudden release of energy from a fission reaction. (See also Hiroshima, hydrogen bomb, Nagasaki, and Strategic Arms Limitation Talks [SALT].)
