Research article | 23 Feb 2016 . Speciation of 127 I and 129 I in atmospheric aerosols at Risø, Denmark: insight into sources of iodine isotopes and their species transformations We present an application of multi-isotopic fingerprints (i.e., 236U/238U, 233U/236U, 236U/129I and 129I/127I) for the discovery of previously unrecognized sources of anthropogenic radioactivity. Our ^129I results indicate that Fayetteville experienced a two- stage irradiation with 4-pi production dominating in both bombardments. In this scenario most of the ^129I and cosmogenic noble gases were produced at or below a depth of 20 cm in a large body during a 25-40-m.y.
1996-12-20 · The 129I/127I ratio in twin water collected during the same period was found to be as high as 1.7 x 10(-8) and it is supposed to be the predominant source of 129I in the biosphere. 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.
The 129I concentrations and 129I/127I ratios decreased exponentially with the depth, and 2 orders of magnitude lower in the deepest layer (60 and 90 cm) compared with the top layer, indicating a significant contribution of anthropogenic input in the upper layer, and high retention of 129I in soil.

Iodine, isotope of mass 129, at. 129I Signal Intensity 129I BEC (ppt) Oxygen CCT Gas Flow (ml/min) 10ppb 127I (cps) 129I Background (cps) 129I BEC (ppt) Figure 2. Comparison of different manually tuned settings for the CCT gas flow. Results A mass spectrum of the region between m/z 120 to 140 is shown in Figure 1 for the three different measurement modes used. Radiation dose from the long-lived radioisotope of iodine (129 I, with the half-life of 1.6 × 10 7 years) that is released from spent nuclear fuel reprocessing plants constitutes a significant portion of the public dose due to nuclear facilities (Müller and Pröhl, 1993, UNSCEAR (United Nations. Our ^129I results indicate that Fayetteville experienced a two- stage irradiation with 4-pi production dominating in both bombardments.

Scarcity of data on 129I from the Pacific, Indian and South Atlantic Oceans demonstrates gaps in the coverage of the isotope spatial extent. These shortcomings in the spatial coverage may relate to the understanding that the anthropogenic 129I signal will take a long time to be transported, if at all, from the North Atlantic into other oceans. 1996-12-20 · The 129I/127I ratio in twin water collected during the same period was found to be as high as 1.7 x 10(-8) and it is supposed to be the predominant source of 129I in the biosphere.
