The Comparative Estimation of Animal Radiosensitivity.

Technogenic environmental pollution is the factor of destabilization of natural and agricultural ecological systems. Among various kinds of beings agricultural animals are considered as one of the most vulnerable components of ecosystems to the influence of technogenic factors including ionizing radiation. Therefore, the generalization of experimental data and mathematical modeling are necessary to forecast the mortality of irradiated animals.

[Quantitative dependence of sheep death on dose and dose rate of external gamma-radiation].

The results of experimental studies of sheep death at different dose rates of gamma-radiation have been analyzed. Parameters of a mathematical dependence of animal death on the exposure dose and dose rate have been identified. The evaluation of adequacy of the derived equation has demonstrated that the established relationship correctly describes the experimental data in studied dose rate range.
