抄録

Palladium was chosen for the investigation of the effect of γ-radiation on absorption of hydrogen in metals. The amount of hydrogen in palladium can be estimated by the change in electrical resistance. No absorption of hydrogen was observed during irradiation even for a long time, when palladium wires were immersed in acidic or alkalic solutions. On the other hand, palladium with thin oxide films formed either by the anodic treatment or by γ pre-irradiation in aerated water or in hydrogen peroxide, absorbed a large amount of hydrogen in dilute sulfuric acid or in dilute hydrochloric acid. From these results, it is concluded that a thin oxide film is necessary for absorption of hydrogen by palladium in an acidic solution. But the oxide film formed by heating in air showed no such effect. Probably, such a film may be too thick and too dense to permits permeation of hydrogen ions. The results are interpreted by the photovoltaic theory of semi-conductors.
