ionization

ionization /ion·iza·tion/ (i″on-ĭ-za´shun)

1. any process by which a neutral atom or molecule gains or loses electrons, acquiring a net charge.

2. iontophoresis.

ionization

[ī′ənīzā′shən]

Etymology: Gk, ienai + izein, to cause

the process in which a neutral atom or molecule gains or loses electrons and thus acquires a negative or positive electrical charge. Ionizing radiation produces ionization in its passage through body tissue or other matter. Ionization can also cause cell death or mutation.

1. any process by which a neutral atom or molecule gains or loses electrons, thus acquiring a net charge, as the dissociation of a substance in solution into ions or ion production by the passage of radioactive particles.

2. iontophoresis.

ionization chamber

an enclosure containing two or more electrodes between which an electric current may be passed when the enclosed gas is ionized by radiation; used for determining the intensity of x-rays and other rays.
