Abstract

La présente invention concerne un procédé pour mesurer le degré d'étouffement associé à un échantillon dans un milieu à scintillation liquide. Selon l'invention, on expose l'échantillon à un rayonnement d'une source étalon pour produire une dispersion par effet Compton des électrons ayant une distribution d'énergie d'électrons dispersés par effet Compton ou spectre de la hauteur des impulsions, ce spectre étant défini à son extrémité de forte énergie par une configuration d'un front de Compton; on identifie une caractéristique unique de front de Compton et on mesure la valeur de hauteur d'impulsion qui lui correspond; on compare cette valeur mesurée pour l'échantillon à une valeur de hauteur d'impulsion mesurée pour un étalon de calibrage, la différence des valeurs indiquant le degré d'étouffement dans l'échantillon; la figure 1 montre les comptes par hauteur d'impulsion pour un échantillon étouffé et non étouffé L'invention s'applique notamment aux systèmes de comptage
