Residual hydrogen and helium gases in the materials irradiated in SINQ were measured by two different methods. The results showed that the amount of residual helium gas was within a factor two. For the case of TEM specimens the residual helium gas was scattered within a couple of tens percent in comparison with published data. Residual hydrogen could not be quantified because of measuring accuracy.
