This report introduces a technique known as tritium autoradiography which may be useful in the detection of fatigue damage in metallic components. Tritium autoradiography involves the infusion of radioactive hydrogen tritium into a fatigue damaged structure. The damaged areas of the structure may act as preferred trapping sites for the tritium and as the tritium decays via the emission of beta particles it can be detected using nuclear emulsion film.
