Research Project Outline
For sustainable water use, a technology to diagnose and predict properly whether the water is suitable for human usage is indispensable. This study will develop a simulator which is capable to estimate how fallout radioclides, such as iodine 131 and cecium 137, are transported in the atmosphere, fall along with rainfall, and flow down through streams with sediments. The simulator will also enable us to estimate the timing when these fallout radioclides arrive at the intake of water purification plants and their concentrations. The simulator will support securing the safety of drinking water through temporary shutoff of intakes and/or proactive water treatments, and is expected to contribute for realizing secure and untroubled water use.
