Аннотация: Iodine isotopes (129I and 127I) in the fresh and sea water of Lake Khanka and the Sea of Japan (Peter the Great Bay) were determined. The measured concentration of 129I in the seawater is (1.87–2.33) × 107 atoms/L and (29.0–39.9) × 107 atoms/L in the lake water. The 129I/127I atomic ratios in the fresh water [(0.87–1.13) × 10−8] are two orders of magnitude higher than those in the sea water [(0.91–1.15) × 10−10]. 129I was flowed into sea from the river, deposited and quickly diluted in the seawater, causing a declined 129I concentration. The orders of magnitude higher stable 127I concentration in seawater compared to the fresh water enlarged the difference on the 129I/127I atomic ratios.
