FIELD: nondestructive inspections of objects. SUBSTANCE: method used for nondestructive inspections of uranium oxide fuel elements to determine their gadolinium content involves measurement of inherent background radiation of uranium and its daughter products passed through fuel element can in energy range above energy of gadolinium absorption K edge and below energy of uranium absorption K edge. EFFECT: enhanced precision of gadolinium content evaluation. 1 cl, 3 dwg
