Outline of Final Research Achievements

In this study, we succeeded in estimating the age of spring water and groundwater using Krypton-85 (85Kr) which is a new age tracer all over the world at high time resolution by improving the conventional measurement system.
We conducted field survey in several research areas such as Kumamoto area and Miyakonojo Basin, succeeded in establishing a series of analytical methods and practical application of the 85Kr method. By using the age-cross-check at the same time with other age tracers, validity of the 85Kr method could be verified. The establishment of the 85Kr method with no weak point in the groundwater flowing process has made a new impact on the age dating field.
