To provide a decontamination method in which application of reuse after the decontamination of an object to be decontaminated is not limited and the object to be decontaminated can be easily and inexpensively decontaminated.
The decontamination method according to the present invention peels a harmful substance from an object 100 to be decontaminated by giving a pressure wave 95 generated with discharge to the object 100 to be decontaminated adhered with the harmful substance on the surface of a matter. Further, the value of a grain size set as a border value whether or not to be a decontaminated object is decided as a reference value, and the contaminated soil of an object to be processed is divided into the contaminated soil of a grain group equal to or lower than the reference value and the contaminated soil of the grain group equal to or higher than the reference value, and the contaminated soil of the grain group in which a ratio of the residual radioactivity to the total contaminated soil of the processing object is small and a weight ratio to the total contaminated soil of the processing object is large is defined as the object 100 to be decontaminated from among the contaminated soil of the grain groups divided on the basis of the reference value.
