Contamination survey and decontamination methodology became to be needed, because several robots could not have been decontaminated enough for direct maintenance even after water spray decontamination when robots and robot control vehicles were contaminated during deployment for emergency response to Fukushima Daiichi NPPs accidents. "Basic Decontamination Methodology" was established based on confirmation of water spray effectiveness, specification of parts difficult to decontaminate by water spray and identifying of effective decontamination method for the parts, after investigations of the robots and robot control vehicles deployed for emergency response to Fukushima Daiichi NPPs accidents.
