The behavior of H in stainless steel, Ti and V alloys under treatment with ionizing radiation was studied. It was shown that such radiation stimulated extensive H migration. The cross-section for interaction between accelerated ions and H atoms was estimated to be 10-16cm2. A phenomenological model for ionization-accelerated H migration in metals was proposed. The electron-stimulated and -stimulated dissociation of H-containing bonds in a solid was suggested to involve Mensel-Gomer mechanisms. The calculated probability of H migration, as based upon these mechanisms, was in good agreement with experimental results.
