The relevance of the research is determined by the need to identify the indicator properties of chemical composition of the natural environment components, local and regional characteristics of their composition, taking into account natural and anthropogenic factors of influence in order to conduct environmental assessment and areas subdivision effected by nuclear technogenesis. Environmental zoning of the study areas was carried out only taking into account the dose loads of the population obtained as a result of the activities of the former Semipalatinsk test site. In this regard, it is necessary to study the natural geochemical specifics, which would allow a more accurate approach to the issue of environmental assessment of the studied areas, taking into account the complex impact of natural and man-made factors The main aim of the research is the complex study of the elemental composition of the environment components in the territory adjacent to the former Semipalatinsk Test Site Object of the research is the components of the environment (soil, salt deposits of drinking water, plant), food, biological objects. Methods. Complex of environmental components was sampled in residential courtyards. The main criterion in selection of the investigated residential yards was the fact that the respondents lived there for at least 10 years. After appropriate preparation, the samples of the selected components were studied on instrumental neutron activation analysis The paper introduces the results of a comprehensive study of elemental compositions of the environment components (soil, salt deposits of drinking water, biological objects, food products) that are in contact with them in the zone of influence of the former Semipalatinsk Test Site. Elements-indicators of the nuclear technogenesis effects were identified in the studied environment samples as a regional specificity of the chemical composition of the studied territory show in U and Zn accumulation.
