Protecting your home from radon

According to the U.S. Environmental Protection Agency (EPA), radon is the number one cause of lung cancer among non‐smokers and the second leading cause of lung cancer overall, responsible for about 20,000 lung cancer deaths every year.

Radon is an invisible, odorless, and tasteless gas that comes from the breakdown of uranium inside the earth. It causes no immediate health symptoms. Simple test kits can reveal the amount of radon in any building. In most buildings, levels of radon can be reduced with easy and affordable venting techniques. Homes built on a concrete slab or homes with a basement may also be at a higher risk for radon gas.

Radon levels are believed to vary throughout Clark County, with higher levels in areas bordering the Columbia River. Because of these varying radon levels, Public Health encourages all residents to get their homes tested. Test kits are available at most home improvement stores.
