Description

  TECHNICAL FIELD The present invention relates to a radioactive contamination slope working device capable of performing removal work of soil and the like on slopes contaminated with radioactivity from a place not contaminated with radioactivity or a contaminated place with low concentration of radioactivity. .

  Conventionally, in order to remove the sediment on the ground that has been contaminated with radioactivity, it has to be carried out by wearing radiological protective clothing. Because the time that can be entered in is set, workers who can work gradually have disappeared.

  Moreover, there was no idea of safely removing soil contaminated with radioactivity only by thinking about how to treat radioactively contaminated soil.
