Radon and Ventilation – How They Are Connected Okategoriserade

Radon and Ventilation – How They Are Connected

Radon is an invisible, odorless gas formed when uranium in bedrock or certain building materials breaks down. Because it can easily seep into indoor environments, radon levels are strongly influenced by how homes and buildings are ventilated. Understanding the link between radon and ventilation is therefore essential to preventing health risks and ensuring safe indoor air quality, whether in private…

When should you test for radon? Five key moments

Radon is an invisible, odourless gas that can cause serious health problems if present in high concentrations indoors. It forms naturally when uranium in bedrock breaks down, entering buildings through their foundations, construction materials, or household water supply. As radon cannot be smelled, tasted, or seen, the only reliable way to detect it is to measure its concentration. There are…
