| biospheric 129i concentrations in the pre-nuclear and nuclear age. | in order to detect characteristic regional differences or temporal changes of 129i concentrations in the biosphere, thyroids from humans, grazing livestock, and herbivorous wildlife species (reindeer and roedeer) were collected in various areas of the world which are not affected by reprocessing plants. for reasons of comparison, all samples were analyzed for their 129i:127i atom ratios. human and bovine thyroids taken from the 10th region in southern chile (39 degrees-41 degrees south) indicate ... | 1993 | 8244695 |
| ecological half-time and effective dose from chernobyl debris and from nuclear weapons fallout of 137cs as measured in different swedish populations. | the fallout in sweden of radiocesium from nuclear weapons tests during the 1960's (137cs) and from the chernobyl accident in 1986 (134cs and 137cs) has transferred to humans through different ecological pathways. data from whole-body burden measurements of 134cs, 137cs, and 40k in various swedish populations between 1964 and 2002 have been compiled. this database enables an evaluation of the temporal and geographical dependence of the transfer of radiocesium from ground deposition to humans and ... | 2006 | 16607176 |
