Ecological-biochemical analysis of microtus oeconomus populations state in the territory with increased level of natural radioactivity

Long-term (within 50 years) analysis of radium accumulation in the organism of Microtus oeconomus Pall., living on radioactive zones showed that from 1990-th years for the present time an increase of 226Ra content is observed. In tissue of Microtus oeconomus Pall. from radioactive zones are found both adaptive reorganizations of cellular systems of regulation, and considerable changes of processes of power exchange and lipids peroxidation in tissues, bringing to imbalance and violation of correlative communications of the biochemical indicators, depending on a phase of population cycle and level of radioactive pollution.
