Abstract
THE nature of radiation damage in metals has mainly been inferred from changes in physical properties resulting from irradiation. This evidence cannot generally be interpreted unambiguously. A more direct experimental approach has recently been made possible with the development of the technique of transmission electron microscopy which makes possible the direct observation of dislocations in metals. The damage resulting from neutron irradiation has been examined in a number of metals using this technique. In some metals dislocation loops were observed while in others no structural changes were found subsequent to irradiation. The reasons for these differences in behaviour are not yet understood.
