Thirteen years have passed since the accident at TEPCO's Fukushima Daiichi Nuclear Power Station, but the concentration of radioactive materials has not returned to pre-accident levels in some coastal areas. Therefore, continuous monitoring of radioactive materials is being conducted by ministries, local governments, and electric power companies. In the future, it will be important to centralize the monitoring data collected by each organization and evaluate the results. In addition, unmanned monitoring data acquisition itself has been attracting attention in recent years. In this presentation, we will report on JAEA's efforts to create a database of radioactive materials in coastal area and to develop a technology for measuring radioactivity by unmanned vessel.
