The structure of a cylindrical ionization chamber with a shielding mesh is described. Its sensitive volume is 2 liters and it is filled with xenon at a pressure of 50 atm. The basic characteristics of the detector, such as the energy resolution and efficiency of detection of {gamma}-quanta at different energies, are given. The energy resolution at 662 keV is 4% at the optimal electric field in the chamber. The experimental characteristics of a xenon-filled chamber are compared with those of a conventional NaI(Tl) 200 x 100-mm detector, which is widely used in both geological and ecological studies. Various applications of the cylindrical xenon gamma detector are considered.
