Why should every Marshall home be tested for radon regardless of age?

It is a common misconception that only old homes or homes with basements have radon, but in Marshall and across southwest Minnesota, radon depends on the soil beneath the home and how the house draws air, not on its age or style. A new home in a southeast Marshall subdivision can test just as high as a century-old house near downtown. Radon enters through foundation cracks, sump openings, and slab penetrations, and tight construction plus winter sealing against prairie cold can concentrate it indoors. The Minnesota Department of Health recommends every home be tested, and this region's geology makes elevated readings common enough that you should never assume a home is fine. Because you cannot see or smell radon, testing is the only way to know, and mitigation is straightforward if needed. Make radon testing a routine part of your inspection.
