The distribution of •29I in the major water masses sampled provides an excellent illustration of the unique source function of 1291, which results in stronger labeling of the northern-source overflow Surface seawater samples collected from the North Sea and English Channel were analyzed for total 129I and 127I, as well as for iodide and iodate. Relatively high 129I concentrations (2-3 x 10(11) atoms/L) were observed in the northern part of the English Channel and in the southeastern North Sea. © COMMONWEALTH OF AUSTRALIA, 2010 1298i (Design date 04/10) - Page 1 Citizenship fees Form 1298i www.citizenship.gov.au Telephone 131 880 during business hours in We constrain the last r-process source by comparing the measured meteoritic ratio 129I/247Cm = 438 ± 184 with nucleosynthesis calculations based on neutron star merger and magneto-rotational supernova simulations.

Compared to 127I the fraction of iodide was slightly higher in case of 129I in all waters. 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-129. iodine-129 atom. 15046-84-1.

129I concentrations of 1 to 102 Bq 129I (g thyroid)−1 were found in The use of ICP-MS for determination of 129I in environmental samples is complicated by interference from 129Xe+ originating from Xe present as an impurity in 17 Jan 2021 In addition, the global 129I emissions from land are estimated to be 1.7 GBq/y. The remarkable 129I emission levels from land mainly appear in Transmutation of 129I, 237Np, 238Pu, 239Pu, and. 241Am using neutrons produced in target-blanket system 'Energy plus Transmutation' by relativistic protons. In addition, the bioavailability and radiation toxicity (dose to thyroid) of 129I are discussed. Key words: Iodine-129, speciation analysis, tracer, bioavailability, Data are presented here on the anthropogenic 129I inventory in regions that have been strongly affected by releases from European reprocessing facilities and radiation exposure evaluation during nuclear accidents and nuclear emergency preparedness. Information about long-lived 129I in aerosols is vital for the Iodine-129 (129I) is a long-lived radioisotope of iodine which occurs naturally, but also is of "Global distribution of 129I in rivers and lakes: Implications for iodine cycling in surface reservoirs". Nuclear Instruments an Here we present four coral 129I time series records from: 1) Con Dao and 2) Xisha Islands, the South China Sea, 3) Rabaul, Papua New Guinea and 4) Guam .

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.

iodine-129 atom. 15046-84-1. Iodine, isotope of mass 129, at.

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–).

Read honest and unbiased product reviews from our users. Despite the common incorporation of iodine in the biological cycle and occurrence of huge contamination of the radioactive isotope (129)I in the Baltic Proper, Skagerrak and Kattegat, there is no data on chemical speciation of iodine in these waters.

In all studied water types the main chemical form of both iodine isotopes was iodide; in sea and lake waters by 92–96% and in rain water by 75–88%. Compared to 127I the fraction of iodide was slightly higher in case of 129I in all waters. 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.
