A cleaning method for removing deposition such as scale adhering to the surface of a structure and a structure using this are disclosed. A surface layer that contains a radiocatalyst (5) is provided on the surface of a structure (1). A contaminating substance adhered on said surface layer is decomposed, and/or adhesion of a contaminating substance onto said surface layer is inhibited by irradiating said surface with radiation. A structure corrosion prevention method is also disclosed. A surface layer that contains a radiocatalyst is provided on the surface of a structure, the corrosion potential of said surface being decreased by irradiating said surface with radiation.
L'invention concerne un procédé de nettoyage permettant d'éliminer un dépôt tel que le tartre adhérant à la surface d'une structure, ainsi qu'une structure mettant en oeuvre ce procédé. Une couche de surface contenant un catalyseur radioactif (5) est formée sur la structure (1). Le dépôt adhérant à la couche de surface est décomposé par soumission de la surface de la structure à un rayonnement, et/ou l'adhésion du dépôt à la surface est supprimée. L'invention concerne également un procédé anticorrosion permettant de diminuer le potentiel de corrosion au niveau d'une surface par formation d'une couche de surface contenant un catalyseur radioactif sur une structure et par soumission au rayonnement de la surface de cette structure.
