Across much of the Northern Hemisphere, autumn marks the start of a useful period for measuring radon in homes and workplaces. As buildings are heated and windows tend to stay closed, a long-term measurement can provide a clearer picture of indoor radon levels.
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 homes, apartment buildings, or workplaces.
There are several occasions when a radon measurement in the home is particularly important. For example, it is especially important to test for radon when buying or selling a house, remodelling, changing the home ventilation, or when a radon measurement has not been carried out in the last 10 years.
