The paper deals with the features of chemical elements accumulation in the blood of the population living on the territories close to the former Semipalatinsk nuclear test site. The investigated territories as a result of earlier conducted radioecological research by the legislation of the Republic of Kazakhstan are referred to different zones of radiation risk. As a control area, the settlement of Kokpekty, referring to the minimum radiation risk zone, was chosen with a radiation dose of 0,1 to 7 cSv obtained for the entire test period. The study of the elemental composition of the blood of the population exposed to different dose irradiation on this territory has been carried out for the first time. A comparison was made of the concentrations of 28 chemical elements determined by the instrumental neutron activation analysis in the blood of the population of various radiation risk zones. The summary indicators of chemical elements accumulation in human blood, characterizing the levels of established dose loads of the population, are calculated. Biogeochemical series of chemical elements accumulation in the blood of the population of the considered settlements, relative to the general average on the territory, have been built. The elements that make the main contribution to the total index of chemical elements accumulation in the blood of the population of the investigated radiation risk zones have been established. In general, it has been shown that the elemental composition of human blood can reflect the general radioecological situation of the territory.
