Abstract (en)
[origin: FR2792772A1] The ionization chamber comprises a cathode wire wound on the periphery of non-magnetic insulating disks (36,37) mounted on the ends of an anode (35). The cylindrical ionization chamber has an anode rod (35) surrounded by a cathode (38), both being connected to respective elements of a chamber base flange (41). The chamber has two cylindrical non-magnetic insulating disks (36,37) coaxial with and arranged perpendicularly on the ends of the anode (35), the cathode (38) being in the form of a wire wound on the periphery of the two disks. Independent claims are also included for the following: (i) (i) a measuring system, comprising the above ionization chamber, for measuring the activity of a beta -radiation emitting gas; and (ii) a method of operating the above ionization chamber.
