Abstract


Keywords:
Allium test, Radon in water, Mitotic index, Phase index, Genotoxicity, Cytotoxicity.


In this study, the results of cytogenetic analysis of the influence of various radon activity concentrations in water on meristematic cells of Allium cepa L. are presented. The cytotoxicity and genotoxicity test used in this study was the A. cepa test. To reliably consider the biological effects of ionizing radiation coming from radon, it is necessary to modify this test system, adjust the process of exposing the samples in accordance with the migration potential of radon gas. Evaluation of the cytotoxicity and genotoxicity of radon in water, various parameters of A. cepa L. were analyzed, such as root number, mitotic and phase indexes (MI and PI). All applied radon activity concentrations in water, ranging from 100.62 to 1,006.25 Bq/L, caused inhibition of root growth, reduction of mitotic index (MI), and a significant increase in the number of aberrant cells, in the treated meristematic cells of A. cepa L..
