The production of ions in the atmosphere by the loss of an electron from a molecule, typically, for example, by cosmic rays or cosmic radiation.

Radioactivity at the surface can also produce ions in the lowest layer of the atmosphere.
See ionization.

  1. The spontaneous transition of an atomic nucleus to a lower energy state (radioactive decay) accompanied by the emission of an alpha particle, a beta particle, or gamma radiation.
    Alpha emission results in a reduction of atomic number by two and mass number by four; (negative) beta emission results in an increase of atomic number by one but no change in mass number; in gamma emission, atomic number and mass number are unchanged. Several naturally occurring isotopes are radioactive, including carbon-14 and potassium-40, which reside in the human body. Radon (strictly, radon-222) is a natural radioactive gas originating ultimately from the radioactive decay of uranium-238. Artificial radioactivity, as opposed to natural radioactivity, is a consequence of bombardment of isotopes that are not radioactive with neutrons, protons, and other subatomic particles.
    See half-life.
  2. (Often simply activity.) Rate of decay of a radioactive isotope.
    The unit of radioactivity is the curie.
