In Fukushima, evacuation orders have been lifted with the progress in decontamination. Assessment of exposure doses and risk communication with residents are important requirements for the lifting of evacuation orders. This study established three simulation systems were to evaluate external exposure doses based on behavior of residents and integrating ambient dose rate at each location, depending on the objects of the evaluation. Some systems have been applied to local government for risk communication with residents and will relieve residents and help their return.
