Hydrogen depth profiles have been measured for stainless steel pre-irradiated with 10 keV helium ions with fluences close to the critical fluence, Fc. The hydrogen retention was stable with time at room temperature for the fluence above Fc. The retention was composed of the decay and stable components for the fluence below Fc. The annealing up to 400 °C indicated the same release behavior for the fluences below and above Fc.
