an apparatus for detecting and analyzing ionizing radiation, consisting of a vessel filled with a gas at normal or lower than normal pressure and fitted with two electrodes such that the current between the electrodes is a function of the amount of ionization of the gas.
a device for detecting and measuring ionizing radiation, consisting of a tube containing a low pressure gas and two electrodes between which a high voltage is maintained. The current between the electrodes is a function of the intensity of the radiation
ionization chamber n.
A chamber for detecting ionization of the enclosed gas, used for determining the intensity of ionizing radiation.
