Abstract
Examples of using various types of chromosome aberrations as diagnostic indicators for solving practical problems of radioecology are considered. Classifications of chromosome aberrations used to assess the clastogenic effect of radiation and chemical factors and based on cytogenetic studies with solid chromosome staining are analyzed. A certain terminological inconsistency and ambiguity is revealed in the designation of various types and categories of chromosome aberrations that reflect the clastogenic effect. It is shown that inconsistency can hinder the use of cytogenetic indicators in radioecological practice. The original microimages were obtained according to Allium-test with a digital visualization system as examples of aberrant chromosome configuration used for classifications.
