The impact of internal and external physical factors on indoor radon concentrations as a current problem of the health system in the conditions of regional climate change

Climate change may intensify radon migration into homes, increasing health risks. Energy efficiency strategies may contribute to indoor radon accumulation, especially during winter and summer when homes are sealed to maintain thermal comfort balance. Studies from various regions of the world show that meteorological factors influence indoor radon concentration directly or indirectly. Collecting meteorological data simultaneously with indoor radon measurements and studying their relations is essential for understanding these interactions and developing strategies for prevention and adaptation of public health system to future climate. Based on international experience, the methodology for evaluating the influence of meteorological factors on the risk of exposure to radon in a regional aspect was developed.
