[Cytogenetic indices for somatic mutagenesis in mammals exposed to chronic low-dose irradiation]. We used cytogenetic analysis in the studies of the biological effects of a radiation factor of natural and artificial origin (under conditions ofthe 30-km exclusion zone ofthe Chernobyl experimental landfills in Ukraine, Belarus and Russia). The studies have been performed on various types of mammals: domestic animals--cows, pigs, horses and rodents--root voles, the Af mouse line, and yellow necked field mouse, bank voles. We found significant changes in the level of MN and chromosomal aberrations in the animals that were exposed to the conditions of chronic low-dose radiation for a long time ...
[Prediction of 137Cs accumulation in animal products in the territory of Semipalatinsk test site]. The paper describes mathematical models for 137Cs behavior in the organism of horses and sheep pasturing on the bording area to the testing area "Ground Zero" of the Semipalatinsk Test Site. The models are parameterized on the base of the data from an experiment with the breeds of animals now commonly encountered within the Semipalatinsk Test Site. The predictive calculations with the models devised have shown that 137Cs concentrations in milk of horses and sheep pasturingon the testing area to "Ground Zero" can exceed the adopted standards during a long period of time.
[Total Ca contents in blood cells and plasma of the irradiated animals]. It was found that the total Ca content in erythrocytes from irradiated sheep and horses increased by 10-40% from 1st till 5th days after irradiation, the intracellular Mg content being unchanged. More than 2-fold increase in total Ca content in lymphocytes during first 15 days was revealed, while in platelets only a trend for a growth in acute period of radiation disease was detected. On the contrary, no reliable changes in total Ca content in plasma after irradiation were observed. This fact indicates that Ca accumulation in blood cells after whole-body irradiation is due to disturbance in in...
