A review on speciation of iodine-129 in the environmental and biological samples

As a long-lived beta-emitting radioisotope of iodine, 129I is produced both naturally and as a result of human nuclear activities. At present time, the main part of 129I in the environment originates from the human nuclear activity, especially the releases from the spent nuclear fuel reprocessing plants, the 129I/127I ratios have being reached to values of 10−10 to 10−4 in the environment from 10−12 in the pre-nuclear era. In this article, we...
