CAVITY IONIZATION CHAMBERS WITH CONSTANT RESPONSED. Novković, M. Kovačević, D. Veličković, S. Stanković Institute of Nuclear Sciences, Vinča, P.O.Box 522, YU-11001, Belgrade, Yugoslavia The response of ionization chambers made of graphite and air-equivalent material was measured in the X and gamma radiation energy range from 30 to 1250 keV. The energy independent response in the whole energy range was found for the air-equivalent ionization chambers with walls of 2 and 3 mm. The composition of the air-equivalent material was: 0.358 polystyrene + 0.477 graphite + 0.140 Al2O3 + 0.025 Al. Close X |
