PROBLEM TO BE SOLVED: To provide a material hardly taking in a radioactive material such as cobalt 60 or cobalt 58, and to provide a new technology for monitoring its state (adhesion amount or the like), concerning a structure material of piping or the like constituting a reactor. SOLUTION: A reactor structure material is constituted by forming an oxide film containing titanium oxide on the surface to be in contact with a radioactive material of a structure material constituting the reactor. The adhesion amount of titanium oxide is measured by performing light irradiation from a light irradiation device to the oxide film, and by measuring a corrosion potential and/or a current density of the oxide firm.
