Determination of Plutonium Content by Differential Attenuation of Two gamma Rays

摘要

The main interest of this method is the direct measurement of element content in homogeneous liquid or solid. The range concentration of analysis is 10 to 300 g.1 exp -1 plutonium. This nondestructive method allows the plutonium measurement either in situ or in a derivate circuit. The inconveniences are the periodic changes of sources and the working difficulties about the detector. The studies have been made to determine the effect of the heavy elements and of the fission products. An apparatus is now studied and realized for the determination of the plutonium isotopic composition. (ERA citation 09:030412)
