Modeling of radionuclide intake in humans living in the area affected by the semipalatinsk test site

In this study, Bodene village in Beskaragai district of East Kazakhstan Oblast of Kazakhstan was chosen as an object of study because it is close to the site of the nuclear test site and has a large accumulated array of data on the radioecological situation. As part of the study, a questionnaire survey was conducted, which made it possible to compile statistics on the population of the village, as well as on the characteristics of the diet and activities of long-term residents. The work included modeling of technogenic radionuclide intake into a human organism living and carrying out agricultural activity on the territory affected by the Semipalatinsk test site. Calculations are given for intake of radionuclides with plant and animal food, as well as by inhalation. These studies allow to make an assessment and forecast of radiation burden. At the same time it is important to note that no exceedances ofradiation norms have been detected. Contaminated food is the main risk factor for human health, therefore more attention should be paid to monitoring of radiation burden in radioecologically unfavorable areas. The methodology of the study can also be used to control the situation of other settlements, and the results of calculations of this work, in the future, can be used for comparison with the results of biophysical measurements.
