METHOD OF REMOVING POLLUTION ON SURFACE OF BODY POLLUTED BY RADIOACTIVE SUBSTANCE

摘要

PURPOSE:To remove pollution, by rubbing a surface polluted by ice. CONSTITUTION:A surface 4 polluted by radioactivity is rubbed by applying surface pressure a by ice, and clean water is flowed on said surface, thus removing pollution on the surface polluted. This method does not damage the surfaces of objects, which pollution must be removed, and ensures the efficiency of removal higher than that in case of only rinsing by its polishing action. Since a surface of ice contacting with a surface, which pollution must be removed, dissolves due to the heat of friction and the new surfaces of ice are continually formed, the re-adhesion of polluting nuclides is removed.
