Abstract:The article presents the results of the study of geochemical peculiarities of iodine distribution in natural waters of Bryansk region, the most part of which suffered from radioiodine contamination during the accident at the Chernobyl Nuclear Power Plant. The article shows that drinking water generally has low iodine content (below the sanitary standard equal to 10 µg/l). The deep artesian waters of the upper Devonian complex are comparatively most enriched with it (Ме=8,15 µg/l). Thermodynamic modelling has confirmed the possible predominant form of iodine migration and the formation of its mineral (CaI+, CaI2, etc.) and organo-mineral complexes, which promote the removal of the traced element from aqueous. Thus, iodine and its radioactive analogues intake with local drinking waters into the human body largely depends on particular geochemical conditions in the “water-rock” system.
