Abstract

946,807. loriization counters. UNITED STATES ATOMIC ENERGY COMMISSION. June 5, 1961 [June 22, 1960], No. 20190/61. Heading H1D. [Also in Division G1] A gamma radiation detector comprises a gasproportional counter 14 at least partly screened by a material 18 which moderates γ-rays of 0.5 to 5 Mev. energy by the Compton scattering process. The counter preferably comprises a stainless steel wire anode disposed along the axis of a cylindrical envelope of aluminium, or glass having an opaque silver coating, which constitutes the cathode. External electrical leads and end portions of the cathode are shielded with aluminium foil. The tube contains 95% xenon and 5% CO 2 at a pressure of 1¢ atmospheres. The moderator is preferably of carbon and may be formed with one or more slits 19. Alternatively, a multi-slitted cylindrical moderator 22, Fig. 4, may be used, the slits not being diametrically opposed.
