Abstract
In order to understand the effect of beta-rays from strontium-90 (Sr-90), one of the radionuclides released in the Fukushima Daiichi Nuclear Power Plant accident, on corrosion of stainless steel, we have conducted a immersion test of Type316L stainless steel in which Sr-90 was dropped into artificial seawater. We have found that the drop of Sr-90 increased the potential of SUS316L steel, which was caused by an increase in the concentration of hydrogen peroxide in the solution due to beta-rays.
