Features of functional activity of blood cells of sheep in the zones with various density of contamination with 137Cs

The research was devoted to the definition of the extent of the influence of small doses of radiation on kinetics of generation of free forms of oxygen in peripheral blood of sheep. Agrobiocenoses with additional technogenic loading and without it were allocated on the territory of Krasnoyarsk Region. The research was conducted during the period of 2016-2018 in Sukhobuzimsky area of Krasnoyarsk Region in B. Balchug and Minderla villages. Radiometric and spectrometric methods were used for technogenic impact evaluation. The work was performed on 30 heads of small stock from private farmsteads, blood samplings were taken in spring and autumn in 2018. Hematological and immunobiological indicators were analyzed in the study. The level and intensity of active ROS production in sheep peripheral blood were determined by chemiluminescence method. As a result it was established that specific activity of 137Cs in the soils of agro-ecosystems in B. Balchug village was significantly higher than corresponding figure of the soils in Minderla village...
