title: [The cytogenetic monitoring of the environmental conditions on the territories exposed by the radioactive contamination as a result of Chernobyl Nuclear Power Station accident (colony Urazovo Belgorod region as an example)].
abstract: Cytogenetic characteristics of the seed progeny of birch (Betula pendula Roth), growing in colony Urazovo Belgorod region exposed by the impact of Chernobyl precipitation in 1986, were determinated. The changing of cytogenetic characteristics in comparison with the control (mitotic index and level of mitosis pathologies grown, their spectrum widens part of persistent nucleolies at the stages of metaphase, anaphase, telophase of mitosis enlarges, square of surface of single nucleolies decreases, part of moderate-active nucleolies "bark-core vacuolisated" type increase) on the experimental squares is revealed. The most considerable effects were observed in 2000, which connected with the increasing of the contaminations of mentioned territory as a result of brick factory work. By means of cluster analysis methods it was established that the cleanest in northwestern part of colony Urazovo, the most contaminated is central part. It was purposed, that chemical compounds, are main agents caused the changing of cytogenetic properties of test-object after the normalization of the radiation level.
