Eudora sits in eastern Douglas County along the Kansas and Wakarusa rivers, roughly 8 to 10 miles east of Lawrence on K-10. Like the rest of the county, it falls in EPA Radon Zone 1, the category with the highest predicted indoor radon levels. We are not aware of reliable town-level radon figures for Eudora, and the EPA is clear that a county zone does not predict the level in any single house. The only way to know your home's number is to test it.
German immigrants founded Eudora in 1857, and the city incorporated in 1859, so the blocks around downtown include some of the oldest houses in the county. Much of the town is far newer. Census counts show the population roughly doubled between 1990 and 2020, from about 3,000 to 6,408 residents, as K-10 made Eudora an easy commute to Lawrence and the Kansas City area. That mix means radon questions in Eudora often come from two very different kinds of homes.
A common assumption in a growing town is that a newer house will not have a radon problem. Age is not the deciding factor. The Kansas Radon Program explains that radon comes from uranium and radium in the soil, and that soil chemistry varies from one house to the next. The EPA says every new home should be tested as soon as possible after move-in, even if it was built with radon-resistant features.
If you bought a newer Eudora home, look for a capped or labeled PVC pipe running from the basement floor up through the roof. That may be a passive radon-resistant system. If a test comes back high, the EPA notes a fan can often be added to make the system active, which is usually simpler than starting from scratch.
Older houses can have block or stone foundation walls, crawl spaces, sump pits, or additions built on a different foundation than the original house. None of these means radon is high. They do affect where a test device should go and how a mitigation system is designed, since each foundation area may need its own approach. A KDHE certified professional will look at these details during a site visit. See how radon mitigation works.
Eudora is a family town. In the 2020 Census, 42% of households had children under 18, and students attend Eudora USD 491. The Kansas Radon Program suggests that people with young children take radon especially seriously, because lung cancer risk builds over decades. If kids sleep or play in a finished basement, test on that level. The EPA also recommends testing before you finish a basement and again after the work is done.

Eudora is in Douglas County, which the EPA classifies as Radon Zone 1, its highest potential category. That is a county-level prediction, so the only way to know your home's level is to test.
Yes. Radon depends on the soil under the house, not its age. The EPA says every new home should be tested soon after move-in, even one built with radon-resistant features.
