PROBLEM TO BE SOLVED: To facilitate repair and preventive maintenance treatments for radioactive material handling facilities under normal work environment while shortening the process, reducing the exposure to radiation, and eliminating the need for expertise. SOLUTION: In this method, a high-strength resin which satisfies specifications of resistance to radiation, resistance to heat, and tensile strength is previously formed into a sheetlike or paste-like form, and the workpiece is applied directly to SUS steel, general steel products, concrete, etc. at atomic power plants, facilities, etc. which handle radioactive materials.
