SURFACE 129IODINE/127IODINE RATIOS: MARINE VS. TERRESTRIAL

摘要: Redistribution of anthropogenic 129I from the main source area in northeast Atlantic is by atmospheric and ocean current transport. While atmospherically-delivered leached continent has raised ratios measured rivers southern U.S., global flux to sea little influence on marine ratios. 129I/127I 127I concentrations soils suggest a residence time for soil iodine 30 100 years. Significantly lower ambient stable (127I) terrestrial environment result higher fresh waters than water.
