Quantitative Analysis of Fission Products by $gamma$-Spectrography; ANALYSE QUANTITATIVE DES PRODUITS DE FISSION PAR SPECTROGRAPHIE $gamma$
The activity of the fission products present in treated solutions of irradiated fuels is given as a function of the time of cooling and of the irradiation time. The variation of the ratio (Ce/sup 144/ + Pr/sup 144/ activity)/(Cs/sup 137/ activity) as a function of these same parameters is also given. From these results a method is deduced giving the age'' of the solution analyzed. By gamma -scintillation spectrography it was possible to estimate the following elements individually: Ce/sup 141/, Ce/sup 144/ + Pr/sup 144/, Ru/sup 103/, Ru/sup 106/, Cs/sup 1 Zr/sup 95/ + Nb/sup 95/. Yield curves are given for the case of a single emitter. Of the various existing methods, that of the least squares was used for the quantitative analysis of the fission products. The accuracy attained varies from 3 to 10%. (auth)
