Abstract
Radiation effects on reproduction have been studied in root voles from areas with increased contents of heavy natural radionuclides (HNRs). To assess reproductive parameters in a population exposed to radiation over many generations, two experiments have been performed at an interval of 25 years (in 1984 and 2009). The observed intensification of reproductive processes (in particular, an increase in the proportion of females and their fecundity) is evidence for an adaptive response of the population to chronic low-intensity irradiation that is aimed to counterbalance high embryonic and postnatal mortality. However, the results of inbred crossing confirm that heritable genetic damage caused by exposure to environmental HNRs is detected in the population even after 100 generations.
