摘要：

We estimated the groundwater age from Ra-228/Ra-226 ratios in young groundwater and relevant rocks in the volcanic area of the Kakitagawa River around Mount Fuji, Japan, and compared our results with those from H-3/He-3 age determination. The groundwater residence time estimated from the Ra-228/Ra-226 activity ratio in groundwater and relevant rocks agreed well with the H-3/He-3 age, suggesting that the Ra-228/Ra-226 ratio of groundwater can be used to estimate residence time of young groundwater in volcanic areas.
