Abstract

UN APARATO Y UN METODO PARA MEDIR LA ACTIVIDAD DE MUESTRAS RADIACTIVAS QUE CONTIENE UN MULTIPLO DE ISOTOPOS RADIACTIVOS. EL APARATO COMPRENDE UNA MEMORIA CON ESPECTROS ALMACENADOS DE RENDIMIENTOS DE RECUENTO CONOCIDOS Y NIVELES DE EXTINCION CONOCIDOS PARA LOS ISOTOPOS QUE HAN DE MEDIRSE, MEDIOS PARA EXTRAER DE DICHOS ESPECTROS UN ESPECTRO DE REFERENCIA REPRESENTATIVO DE UN ESPECTRO DE ISOTOPO PURO A DICHO NIVEL DE EXTINCION DETERMINADO, Y MEDIOS PARA DETERMINAR PARA CADA ESPECTRO DE REFERENCIA EXTRAIDO UN FACTOR POR EL CUAL HA DE MULTIPLICARSE DICHO ESPECTRO DE REFERENCIA EXTRAIDO, ESTANDO CADA FACTOR CITADO RELACIONADO DIRECTAMENTE CON LA CANTIDAD DE CADA ISOTOPO EN LA MUESTRA. EL METODO COMPRENDE LLEVAR A CABO CADA UNA DE LAS OPERACIONES REALIZADAS CON LOS COMPONENTES DEL APARATO, ANTES COMENTADOS.
