| Summary: | Заглавие с экрана The peculiarities in thorium and uranium distribution in various media (soil, drinking water, scale, hair, blood, biopsic specimen of pathologically changed thyroid gland) from 16 regions of Tomsk Oblast of Russian have been analyzed. Besides, the values of their concentrations and Th/U relations have been stated for indication of changes in conditions of not only outside an organism but also inside it. The basic research method is neuron-activation analysis made in the nuclear-geochemical laboratory of the Geoecology and Geochemistry Department. The analysis of spatial distribution of radioactive elements over the territory of Tomsk Oblast as well as region ranking indicators of system interaction allows for reveling different mechanisms of entry, distribution, and accumulation of uranium and thorium in living systems. Their accumulation in accumulative media - hair, in pathological thyroid forms - indicates the fact that the elements entering with water, from soil via trophic chain or air are not excreted, but stay in the organism. |
