Disclosed are a radioactive decontamination device and a radioactive decontamination method, each capable of efficiently and overall reducing the radioactivity level of a radioactive contaminant. The present invention provides a radioactive decontamination device for reducing the radioactivity level of a carbonized radioactive contaminant (B) having a radioactive material, which includes a stirring container (41) for stirring the carbonized radioactive contaminant (B), a discharge feeder (42) for discharging the stirred carbonized radioactive contaminant (B) which is disposed below the stirring container (41), wherein the stirring container (41) is provided with a nozzle (45) for spraying an aqueous solution (44) containing photosynthetic bacteria over the carbonized radioactive contaminant (B) to be fed into the stirring container (41). |
