Radioactivity is the spontaneous disintegration or decay of the nucleus of an atom by emissions of particles, usually accompanied by electromagnetic radioation. The energy produced by radioactivity has important military and industrial applications. However, the rays emitted by radioactive substances must therefore be handled with extreme care (radioactive waste).

Radioactive Links Natural radioactivity is exhibited by several elements, including radium, uranium, and other members of the antinide series, and by some isotopes of lighter elements, such as carbon-14. Carbon-14 is used to date artifacts and bones. |
