Effect of ⁹⁰Sr Dissolved Solution on Corrosion Potential of Type 316L Stainless Steel

Abstract

In order to analyze the effect of β-rays on corrosion, the effect of dissolved ⁹⁰Sr on the corrosion potential of Type 316L stainless steel was investigated. The ⁹⁰Sr-containing HCl was dropped into the diluted artificial seawater while the corrosion potential was measured. The solution was dropped in two times and the radioactivity of the solution was adjusted to be 0.15 MBq and 1.5 MBq, respectively. As a result, it was found that the potential of Type 316L stainless steel was increased by the drop of ⁹⁰Sr-containing HCl.
