Abstract

Indoor radon concentrations have become a significant health concern due to their long-term deleterious effects on the lungs. Radon exposure is a leading cause of lung cancer, especially among non-smokers, making it critical to understand the risk factors associated with radon presence. This article evaluates radon levels in a single-family house located to the northwest of Madrid. The study was conducted during both summer and winter seasons, which are the predominant periods for this region. The research aims to analyze the varying radon concentrations observed during these seasons, considering factors such as ventilation, seasonal temperature differences, and the specific construction materials used in the house. The accumulation of radon can be influenced by the permeability of the building’s foundation, materials, and the effectiveness of natural ventilation systems. In winter, reduced ventilation can lead to higher radon levels due to the sealing of windows and doors to retain heat, while summer conditions may provide more opportunities for ventilation, potentially reducing concentrations. This study examines how these factors interact, exploring the relationship between indoor air quality and radon levels. Measurements before and after ventilation renewal are included to assess any changes in radon concentrations. The findings aim to provide a better understanding of the behavior of radon in residential settings and offer practical recommendations for mitigating its health risks, especially in homes with poor ventilation and specific construction characteristics. Ultimately, the results could guide strategies for improving indoor air quality and reducing radon exposure in similar homes.
