Needs assessment and prototype of a low-cost radiation monitoring system for citizens in Fukushima

Based on a questionnaire survey of approximately 1,500 child-rearing people living in Fukushima Prefecture, we developed a prototype of a new radiation visualization system required by citizens. The demonstration test results confirm that the system works properly in high-dose areas in Fukushima Prefecture. The system is expected to provide local residents with a quantitative monitoring of natural decay and decontamination results and reassurance that they can return to their original land and live in peace.
