<p>PROBLEM TO BE SOLVED: To provide a method and an apparatus for cleaning a radioactive material, for cleaning a road surface contaminated with radioactive materials and collecting the radioactive materials.SOLUTION: The cleaning method for a radioactive material uses: a cleaning liquid supply device A1 including a cleaning liquid storage tank T1 and a high pressure pump for boosting a cleaning liquid; a road surface cleaning device A2 connected to the device A1, for cleaning a road surface; and a collecting device A3 for sucking and collecting a contaminated liquid after cleaning. The road surface cleaning A2 includes a self-start driving unit, a cover for covering the whole device excluding a bottom surface, a cleaning nozzle body for jetting a high-pressure cleaning liquid, and a suction port for sucking radioactive materials. Polyionic liquid is used for the cleaning liquid.</p> |
