Abstract
Results of research of hoofed animals in the lands of Zhitomyr Polesye contaminated with radionuclides in result of Chernobyl accident disaster are summarized. During 6–7years after Chernobyl accident gradual increase of population of boar and elk was registered with further stabilization. Population of roe deer continued to increase. Population growth of hoofed animals is connected with disappearance of trouble factor, absence of amateur and industrial hunting, and poaching. Hereinafter, increase of wolf population brings to decrease of hoofed animals populations, which is supported by data on boar. Peculiarities of 20-years dynamics of radioactive contamination of organs and tissues of wild hoofed animals on the example of wild boar are presented. Gradual decrease of radioactive contamination of boar meet and its periodical increase every 7–8 years is observed. It is explained by cyclic change of 137Cs content in fodder plants of these animals, which in turn depends on radionuclides migration in forest ecosystems. Peculiarities of dynamics of 137Cs content in organs and tissues of wild boar in different seasons are revealed. It is explained by annual dynamics of animals’ ration as well as radioactive contamination of fodder plants. Dependence between density of radioactive contamination of soil and coefficient of 137Cs transition to meet of boar was evaluated.
