Radioactive iodine ( $^{129}$ I) is one of the available indexes of long-term migration of groundwater solutes, because of its long half-life (15.7 million years) and low sorption characteristics. All rock and groundwater samples were collected at Horonobe underground research center. Species of iodine in groundwater was mainly I $^{-}$ . $^{129}$ I/ $^{127}$ I isotope ratios in groundwater were lower than that in rocks and almost constant at various depths, demonstrating that iodine in groundwater was released from deeper than co-existing rocks.
