The iodine isotopic ratio (129^I/127^I) and the iodine concentration in hot spring water samples collected from Hokkaidio, Japan were measured. They can be categorized into two groups, i.e., one with 12^9I/127^I ratio of 10^-13 order and the other with 10^-14 order. The age calculated from the iodine isotopic ratio tends to be older than the geologic age. The iodine isotopic ratio (129^I/127^I) and the iodine concentration of river water samples collected after the Fukushima Daiichi Nuclear Power Plant accident can be explained as a mixture of contaminated rain and natural ground water.

测定了日本北海道温泉水的碘同位素比值（129^I/127^I）和碘浓度。它们可以分为两类，即，一种12^9 I/127^I比值为10^-13量级，另一种为10^-14量级。根据碘同位素比值计算的年龄往往比地质年龄更老。福岛第一核电站事故后采集的河水样品的碘同位素比值（129 ^I/127 ^I）和碘浓度可以解释为污染雨水和天然地下水的混合物。
