title: [Role of polyalternativeness of animals' ontogeny development in the estimation of ionizing radiation consequences].
abstract: The role of polyalternativeness of small mammals' ontogeny development (belongings of individuals to alternative pathways of the ontogeny development) in the estimation of effects of ionizing radiation is considered. It is shown that biological consequences of acute (laboratory experiment) and chronic (inhabiting the Eastern Urals Radioactive Trace zone) ionizing radiation in rodents significantly depend on the belonging of individuals to the pathway of ontogeny. Specificity of the response of the population to acute and chronic irradiation is revealed. It is concluded that it is necessary to take into account the belonging of individuals to the pathway of ontogeny development in a wide spectrum of investigations at the analysis of any biological parameters in small rodents in the zones of local technogenic contamination.
