title: [Mechanism of induction of cytogenetic damage in plant meristematic cells caused by combined effect of heavy natural radionuclides and heavy and alkaline metals].
abstract: The analysis of experimental data on the combined effect of 232Th and water from melted snow containing metal ions from industrally loaded territories on Tradescantia (clone 02) and on Allium shoenoprasum meristematic root tip cells treated with heavy natural radionuclides from natural water sources in the area of radioactive wastes storehouse is presented. It was demonstrated that plant meristematic cells response to heavy metals and heavy natural radionuclides, both from two-component model system and from natural water sources, have commom features.
