The 129I concentrations in these mammalian thyroids are similar to those of non-direct contamination areas of the world, where the terrestrial 129I contents are influenced by the global fallout. Finally, we present 129I depth profiles from five stations from this cruise which form the basis for future studies of ocean transport and mixing process as well as estimations of the total budget of 129I released into the Pacific.}, doi = {10.1007/s10967-012-2217-9}, journal = {Journal of Radioanalytical and Nuclear Chemistry}, number = 2, volume = 296, place = {United States}, year = {Tue 129I in Missouri thyroids. Oliver LL, Ballad RV, Manuel OK. Concentrations of 129I and values of the 129I/127I ration are reported in one sample of indigenous vegetation and in over forty additional individual thyroids of man, wild deer and beef cattle in Missouri. Atmospheric 129I deposition was studied in different locations of Japan (Akita, Tsukuba, Tokyo, and Ishigaki Island) with samples collected between 1963 and 2005 in order to understand the distribution and sources of this nuclide and provide a reference deposition level prior to the Fukushima accident. Over this time period, the deposition pattern of 129I in Tsukuba and Tokyo (on the Pacific The 129I was measured by accelerator mass spectrometry (AMS) whereas 127I was measured by an ICP-MS . The results reveal considerable differences of 129I concentration and its species in terms of spatial and temporal variability.
We studied the yields of several short half-life iodine isotopes produced by transmutation of long half-life iodine isotopes obtained from nuclear reactor waste Follow live tweets with #129I @ 2:30pm ET · Matt Herod November 16, 2015. My PhD defence is this week (Wednesday) at 2:30pm ET Iodine-129 (129 I) is a long-lived radioisotope of iodine which occurs naturally, but also is of special interest in the monitoring and effects of man-made nuclear fission decay products, where it serves as both tracer and potential radiological contaminant.

Iodine-129 (129I) Iodine-129 (129 I) is a rare long-lived radio-isotope of Iodine.Iodine-129 called a cosmogenic nuclide, because it is created by energetic cosmic rays impacting matter in a fission reaction, called spallation. Abstract We present an initial characterization of the input of 129 I into the Pacific Ocean resulting from the 2011 Fukushima nuclear accident. This characterization is based primarily on 129 I measurements on samples collected from a research cruise conducted in waters off the eastern coast of Japan in June 2011. Atmospheric 129 I deposition was studied in different locations of Japan (Akita, Tsukuba, Tokyo, and Ishigaki Island) with samples collected between 1963 and 2005 in order to understand the distribution and sources of this nuclide and provide a reference deposition level prior to the Fukushima accident.
Radioiodine (129I) poses a risk to the environment due to its long half-life, toxicity, and mobility. It is found at the U.S. Department of Energy Hanford Site due to legacy releases of nuclear wastes to the subsurface where 129I is predominantly present as iodate (IO3–).
