(also atomic bomb)

    • ‘Britain developed its own atom bomb to remain a great power and avoid complete dependence on the United States, which was refusing to share atomic information.’
    • ‘The blast was 600 times as violent as the Hiroshima atom bomb and shot a nuclear cloud more than 17 miles high into the air.’

    • ‘He recalled, almost apologetically, how beautiful the atom bomb was, marveling at how every color imaginable burst forth upon detonation.’
    • ‘The simple atom bomb owed its explosive power to the energy released by nuclear fission, or fusion.’

Such a bomb contains a critical mass of a material such as uranium-235 or plutonium-239, which when detonated by a conventional explosive charge is capable of maintaining a nuclear chain reaction, releasing large amounts of energy almost instantaneously
