Corrosion experiment for Ta and Hastelloy-B was performed by -ray irradiation under co-existence system of tertiary pyridine type resin and HCl media. As a result, Ta showed perfect anti-corrosion property under all experimental conditions. On the other hand, it was clear that the corrosion rate of Hastelloy-B was proportion to -ray intensity. It is expected that oxidative species, such as hydrogen peroxide and ozone, were produced by irradiation, and were affected to corrosion.
