“…We revealed [13] that mole-voles from the EURT zone did not display any signs of damage of their most radiosensitive systems (haemapoiesis and immunity) while inhabiting the more radioactively contaminated plot than mice and voles did (table 2). They also did not show any morphological anomalies of blood cells as well as any differences by the frequency of chromosomal aberrations [14].…”

“…For quite a representative series of tests of rodents (51 samples from which 25 are original data) we have established that mole-voles were the most radiosensitive specie [11]. Radioresistance of wood mice was 1.4 times higher, whereas field mice and northern red-backed voles were 2-2.5 times more radioresistant than mole-voles (table 1).…”

“…On the contrary, mice and northern red-backed voles from the EURT zone (more than 100 generations since 1957) displayed multiple alterations in the haemapoietic system, delays in the maturation of erythropoietic cells in the bone marrow, increase in the frequency of cells with micronuclei and the general lowering of the immune system functional activity (table 2) [13]. Besides, the ratio of small lympholeukocytes (the most active immunocompetent cells) in mice and voles was lowered, the number of structural anomalies of leukocytes increased, and some signs of violation of mitosis as well as some indications of haemopoietic process being more tensions were detected.…”

Abstract.Results of radioecological investigations of rodents having different ecological specializationwood and field mice, northern red-backed voles and mole-voles to acute (laboratory experiment) and chronic (long-term inhabiting the East Ural Radioactive Trace -EURT) irradiation are summarized. These species are greatly distinguished by a way of life, a migratory activity, an average life span etc. Numerous immunological, hematological and cytogenetical disturbances were found in more radioresistant wood and field mice and northern red-backed voles inhabiting the EURT zone (density of soil pollution by 90 Sr − 18.5 MBq/m 2 = 500 Ci/km 2 ) as compared with the reference samples. On the contrary there were no pathological shifts in more radiosensitive mole-voles from the more radioactively contaminated site ( 90 Sr − 37 MBq/m 2 = 1000 Ci/km 2 ). The absorbed dozes during the life for the mole-voles from the EURT zone were significantly higher (in 30 times) than these ones for mice and voles. These data testify about the possibility of radioadaptation in a series of generations in mole-voles that developed due to their ecophysiological features and isolation of settlement in the radiocontaminated zone. Mice and voles form a flowing population and slip off the prolonged influence of a damaging factor, this circumstance prevents the development of radioadaptation.
