ionization

 [i″on-ĭ-za´shun]
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.

i·on·i·za·tion

(ī'on-i-zā'shŭn),
1. Dissociation into ions, occurring when an electrolyte is dissolved in water or certain liquids or when molecules are subjected to electrical discharge or ionizing radiation.
2. Production of ions as a result of interaction of radiation with matter.
3. Synonym(s): iontophoresis

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

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.

(ī'on-ī-zā'shŭn)
1. Dissociation into ions, occurring when an electrolyte is dissolved in water or certain liquids or when molecules are subjected to electrical discharge or ionizing radiation.
2. Production of ions as a result of interaction of radiation with matter; process by which a neutral force becomes either positive or negative.

ionization

The state of an atom or group of atoms that has become positively charged by the loss of an orbital electron, or negatively charged by gaining an electron. All body electrolytes such as sodium, potassium, calcium and magnesium become ionized in solution. Gases may be ionized by means of electrical discharges.

ionization (īˈ·n·ī·zāˑ·shn),

n a process wherein an atom or a molecule loses or gains at least one electron to form an ion (a charged particle).

n See chamber, ionization, air-equivalent.
ionization density,
n the number of ion pairs per unit volume.
ionization path (ionization track),
n the trail of ion pairs produced by ionizing radiation in its passage through matter.
ionization potential,
n the potential necessary to separate one electron from an atom, resulting in the formation of an ion pair.

ionization

1. the dissociation of a substance in solution into ions.
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.
