Three frequencies ( colors ) of lasers are used for full ionization of uranium 235.

The control of ionizing and non ionizing radiation the new Law on Protection from Ionization in Republika Srpska, adopts the IAEA recommendations concerning the supervision and control of ionization sources, and it establishes monitoring.

Personal dosimeters allow medical control of persons working on the sources of ionization and radioactive biosphere.

Aeronomy is the study of the upper layers of the atmosphere, where dissociation and ionization are important.

The degree of ionization, formula_1, is defined as formula_2, where formula_3 is the number density of ions and formula_4 is the number density of neutral atoms.

During the entry of a meteoroid or asteroid into the upper atmosphere, an ionization trail is created, where the molecules in the upper atmosphere are ionized by the passage of the meteor.

Auroral particles The immediate cause of the ionization and excitation of atmospheric constituents leading to auroral emissions was discovered in 1960, when a pioneering rocket flight from Fort Churchill in Canada reveealed a flux of electrons entering the atmosphere from above.
