Nuclear Bombs are small atomic warheads powered by a small chunk of fissionable material. Uranium is the most commonly-used element, though most any Radioactive Element could be used with varying degrees of efficiency. Nuclear Bombs give off a tremendous amount of heat, radiation and pressure when detonated, but their area of effect is fairly small compared to superior Mass Destruction Devices.
