AbstractAbstract
[en] This invention concerns a process and system for determining the degree of quenching in liquid scintillation counting samples, in order to overcome the drawbacks of the conventional technique. With this in view, the invention includes a method for exposing a sample to the radiation of a standard source. In this way, a distribution is produced of the electrons scattered by Compton effect, presenting a Compton front as forward front. Then a determination is made of a single characteristic of the Compton front, preferably the point of inflexion when the second derivative of the front is nil. Then the value of the pulse height corresponding to it is determined and this makes it possible to compare the pulse height figure and to determine in a similar manner with a calibration standard the difference in the pulse height figures indicating actual degree of quenching

La presente invention reside dans un procede et un dispositif pour determiner le degre d'etouffement dans des echantillons de comptage a scintillation liquide, de facon a surmonter les inconvenients de la technique conventionnelle. A cette fin, l'invention comporte un moyen pour exposer un echantillon a un rayonnement d'une source standard; on produit aussi une distribution des electrons disperses par effet de Compton, presentant un front de Compton comme front avant; on mesure ensuite une caracteristique unique du front de Compton, de preference le point d'inflexion ou la seconde derivee du front est nulle; puis on determine une valeur de la hauteur d'impulsion qui lui correspond, qui permet de comparer la valeur de la hauteur d'impulsion et de determiner d'une facon analogue avec un etalon de calibrage, la difference des valeurs de la hauteur des impulsions indiquant le degre d'etouffement presentOriginal Title
