atomic bomb

Physics

See nuclear weapons.

Science and Technology

An explosive device that releases energy through the fission reactions most commonly of uranium-235 or plutonium-239. The bomb detonates when a conventional chemical explosion compresses the fissile material into a supercritical mass, in which a nuclear chain reaction proceeds exponentially.
Mike Allaby

Chemical Engineering

A nuclear weapon whose explosive force is due to the energy released through the process of nuclear fission. It involves bringing together a mass of fissile material sufficient to result in a chain reaction that proceeds explosively. Uranium-235 and plutonium-239 are examples of fissile material used in nuclear weapons. The explosive force of nuclear weapons is quoted in kilotonnes or megatonnes of TNT equivalents. The atomic bombs that were dropped on Hiroshima (uranium-235 bomb) and Nagasaki (plutonium-239 bomb) had the explosive energy equivalent to 13 and 22 kilotonnes of TNT, respectively.
