|Definition:|| radiation detector filled with air, a suitable gas, or a gaseous mixture, in which an electric field is provided for the total collection, at the electrodes, of charges associated with the ions and the electrons produced in the sensitive volume of the detector by the ionizing radiation
- pulse ionization chamber,
- integration ionization chamber,
- current ionization chamber,
- free air ionization chamber.
Note 1 to entry: The electric field is not sufficient to produce gas multiplication.
