Efficacité des compteurs à rayons γ

Abstract: Établissement de la courbe d'efficacité des compteurs à rayons γ, à paroi d'Al, Cu, Au, dans le domaine d'énergie o,3-3 MeV, par la méthode des coïncidences et des mesures absolues annexes. Utilisation des divers rayonnements des nuclides : 52V, 28Al, 198Au , 61Cu, Th C". La connaissance de l'efficacité peut donner une présomption de la validité d'un schéma de désintégration encore imparfaitement établi

“…Geiger counters operating at low gas density, electron multiplier tubes, crystal counters, and scintillation counters generally have efficiencies below unity. Gamma-ray counter efficiencies {17, 19,35,37,102,103,116,126,127) are low and depend on the energy and the material of construction. Brass-wall counters of ordinary size have efficiencies of roughly 0.01 times the 7-energy in million electron volts in the range 0.3 to 3 m.e.v.…”
