This article provides strategies for mitigating indoor radon in buildings in the Alto Minho region of Northern Portugal. The techniques explored include soil depressurization, anti-radon coatings and membranes, interior mechanical building pressurization, and natural and forced ventilation procedures. The effectiveness of each technique depends on factors such as indoor radon levels and building construction type. The article emphasizes the potential impacts of soil depressurization and pressurization on soil geotechnical properties. The region of Alto Minho mostly consists of single-family housing with different structures and materials, and an assessment stage is crucial for selecting the appropriate mitigation method. The article also highlights the potential use of anti-radon barriers and mortars in high indoor radon concentration situations, which can be combined with ventilation procedures and real-time monitoring for improving indoor air quality and energy efficiency. The text also provides information about the geological composition of the Alto Minho region, the potential for natural radiation in the region, the predominant types of housing, and the measurement and mitigation of radon. The region is characterized by various types of rocks, including granite, schists, shales, and quartzites, which may contribute to high levels of natural radiation. Traditional stone masonry buildings are common in the region, while modernization has occurred in major urban areas. Radon concentration in indoor environments can be measured using passive or active detectors, and IoT systems offer real-time monitoring and remote access to radon data. The text discusses various mitigation measures for reducing indoor [Extracted from the article] |
