Many published data have demonstrated the potential of radon exposure to induce biological damage. All these studies suggest that exposure to radon and its progeny can represent a significant public health risk. Radon exposure is considered as the second cause of lung cancer and it is the first in never smokers. Many countries have depicted residential radon exposure maps in order to characterize those areas with the highest indoor radon concentrations. There are areas in Kazakhstan with a number of factors leading to natural radioactivity. The genotoxic effects of radon on population of Kazakhstan are poorly understood. These studies conducted in compliance with all requirements of genotoxic studies will provide an extensive and reliable data for a detailed radon zoning of Kazakhstan. Our review attempts to integrate data about the association between residential radon levels and morbidity of population in Kazakhstan. In addition, we tried to cover all points of the cytogenetic and molecular changes induced by radon exposure.
