Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a processing method for reduction in radiation dose of radiation-contaminated soil, radioactive material-containing incinerated ash, or the like being a solid material.SOLUTION: When radiation-contaminated soil, radioactive material-containing incinerated ash, or the like is sprayed with water having fine sintered shell powder mixed in active hydrogen-containing water and is left at rest, an absolute radiation dose of the radiation-contaminated soil, the radioactive material-containing incinerated ash, or the like can be reduced.
