Document Type and Number:
Japanese Patent JP7214448
Kind Code:
B2
Abstract:
To provide a decontamination processing method and decontamination processing device of a contaminated concrete block capable of certainly performing decontamination while simplifying the device, even when a rubble as a decontamination object has blocks having many sizes.SOLUTION: The present invention is a decontamination processing method of a concrete block whose surface layer part is contaminated by a radioactive material. This method includes: a crush process of generating a concrete debris having a predetermined size or less by compressing and crushing the concrete block so as to grasp the concrete block with a tabular body; grinding process of generating a regenerated debris and fine particles by grinding the surface layer part of the concrete debris with a rotating roller; and a separation process for screening the regenerated debris and fine particles with an integrated sieve to separate the regenerated debris from fine particles.SELECTED DRAWING: Figure 1
