PROBLEM TO BE SOLVED: To provide a method for treating an organic substance-containing radioactive solid waste for mineralizing organic substance remaining in radioactive solid wastes in order to store them as a disposed-of material in a final repository site. SOLUTION: This treatment method is characterized by including a crushing process 1 for acquiring granular material of grain size from 0.05 mm to 100 mm by crushing the organic substance-containing radioactive solid wastes, and a thermal decomposition process 2 for thermally decomposing the organic substance in the granular material at temperatures from 400°C to 600°C in an inert atmosphere.
