Autoradiographic methods used for the study of carbon distribution in commercial Zr-2.5% Nb alloy☆

Abstract Methods of activation, contrast macro- and micro-autoradiography and electron-microscope autoradiography were used to study carbon distribution in Zr-2.5% Nb alloy. Their successive usage allows the study of carbon distribution both in macro-areas (up to 1000 cm 2 ) and micro-areas of alloy with a resolution of 0.3 μm.
