PROBLEM TO BE SOLVED: To efficiently remove radioactive materials from contaminated bottom sludge, thereby reducing the volume of objects contaminated with radioactive materials.SOLUTION: A radioactive material removing apparatus 100 removes radioactive materials adhering to bottom sludge underwater in a dammed water area where water is dammed. The apparatus comprises: a storage tank 110 having a transmission part (opening 110a) through which light is transmitted from the outside to the inside; aquatic plants 120 that is housed in the storage tank 110, perform photosynthesis with light transmitted through the opening 110a, and take radioactive materials; a bottom sludge introducing part 130 for taking out contaminated bottom sludge CM to which the radioactive materials have adhered, from the dammed water area, to introduce it into the storage tank 110; and a bottom sludge returning part 180 for taking out decontaminated bottom sludge PM from which the radioactive materials have been removed, due to that the aquatic plants 120 have taken the radioactive materials, from the storage tank 110, to return it to the water bottom. |
