In the decontamination on concrete surface in decommissioning, there is a possibility of cross contamination due to pieces or dust of concrete during chipping. In this study, cross contamination was evaluated by simulated contamination. As a result, it was confirmed that there was no cross contamination on the concrete surface after chipping.
