Abstract

"Sistema de medida de actividad absoluta de radionucleidos por método de coincidencias en centelleador líquido con un cabezal de K fotomultiplicadores de igual eficiencia promedio en cada canal mediante permutación electrónica de los canales". El objetivo del invento es la realización de un cabezal de medida de las radiaciones ionizantes con k fotomultiplicadores con el fin de registrar destellos luminosos producidos en el medio de centelleador líquido. El cabezal puede ser construido de manera que permite obtener valores promediados de los parámetros de señales que aparecen en los canales de medida de un sistema de coincidencias."Absolute activity measurement system of radionuclides by coincidence method in liquid scintillator with a head of K photomultipliers of equal average efficiency in each channel by electronic channel permutation". The object of the invention is the realization of a head for measuring ionizing radiation with k photomultipliers in order to record light flashes produced in the liquid scintillator medium. The head can be built in such a way that it allows to obtain averaged values of the signal parameters that appear in the measurement channels of a coincidence system.
