Individual effective equivalent doses and the elemental composition of human blood

In the article results of researches of elemental structure of a blood of the person at various levels of individual effective equivalent doses of an irradiation, on an example of inhabitants of the territories adjoining to the former Semipalatinsk nuclear test site are resulted. It was revealed that in the blood of residents of compared radiation risk zones compared to the blood of residents with a minimal zone of radiation risk, concentrations of such elements as Na, Ca, Cr, Fe, Co, Br, Cs, La, Ce, Nd, Sm, Eu, Ta, Lu, Au, U have significant differences. All significant differences, with the exception of Fe concentration, are expressed in comparatively high concentrations of these chemical elements in the blood of residents of compared radiation risk zones in comparison with their concentrations in the blood of residents of the minimal radiation risk zone. Fe concentrations in the blood of residents of extreme, maximum and high radiation risk zones are comparatively lower than in the blood of residents of the minimal zone of radiation risk. It was found that the effect of dose loads on the elemental composition of human blood is most clearly reflected at effective equivalent doses above 100 s.Sv. At doses below 100 s.Sv, external factors affecting the elemental composition of human blood are both natural and technogenic. The elemental composition of human blood can have both direct and inverse correlation dependence on the levels of individual effective equivalent doses of human irradiation, which suggests that when assessing the effect of dose loads on the human body, it is necessary to take into account the biogeochemical specificity of the territory of its residence.
