MANHATTAN, Kan. – Radon, a leading cause of lung cancer, is a naturally occurring radioactive element found in the soil; it’s odorless and colorless, but can seep through gaps and cracks in a home’s foundation, said Bruce Snead, Kansas State University Research and Extension residential energy specialist.
When tested, about one in four homes in Kansas will be found to have radon levels at or above four picocuries per liter of air (a scientific measurement), which is the Environmental Protection Agency’s Action Level, Snead said.
Testing for radon is important because the radioactive substance is the second leading cause of lung cancer, he said.
Commercial testing kits are available for purchase at home and hardware stores, and Kansans also may buy a low-cost test kit at county and district K-State Research and Extension offices.
The tests are easy to complete, but it is important to follow the directions exactly, Snead said.
