Description

The importance of knowing the disintegration schema of 99Mo in equilibrium with 99mTc is underlined. By γ spectrometric measurement of the relative γ emission intensities it was possible to determine accurately the absolute of the intensities γ and β transitions; for strong transitions the error obtained is better than one percent. In addition the results of γ intensity ratio measurements are given for the 57Co 122-156 keV emission and the 186Re 123-137 KeV emission. (authors)

Abstract (French)

Le document rappelle la necessite de bien connaitre le schema de desintegration du 99Mo en equilibre avec le 99mTc. La mesure des intensites relatives des raies γ d'emission, par spectrometrie γ, a permis de determiner avec precision les intensites absolues des transitions γ et β; pour les transitions intenses, l'erreur obtenue sur les intensites est meilleure que le pour cent. En outre, les auteurs font part des resultats de mesure des rapports d'intensites des rayonnements γ 122 - 136 keV emis par le 57co, et 123 - 137 keY emis par le 186Re. (auteurs)
