Popis:	The accumulation of 90Sr in the bone tissue of northern mole voles (Ellobius talpinus Pallas, 1770) living under chronic exposure to 90Sr in the center of the Eastern Ural Radioactive Trace (EURT) with a 90Sr contamination density of 37 MBq/m2 or 1000 Ci/km2 has been evaluated. Northern mole voles live under-ground and are characterized by family organization of populations and an extremely weak tendency toward dispersal. While there are no sex- or age-related differences in 90Sr accumulation, sevenfold interindividual differences have been found. Hereditary (familial) determination of the variability of 90Sr accumulation has been demonstrated. The probable causes of the difference in the familial component from the results of laboratory experiments on inbred mice are considered. The age-related inversion of 90Sr accumulation previously found in other mammalian species in the EURT area has been confirmed. A possible mechanism of its formation is suggested.
