In order to evaluate the effect of metal oxidization on wettability enhancement due to RISA, droplet contact angles on specimens of stainless steel (SUS-304), which were oxidized by immersing in a supercritical water were measured at the high temperatures up to 290 ^oC before and after γ-ray irradiation.
