A Quick Primer On Radon

Understanding Radon in Homes

What is radon?

Radon is a naturally occurring chemical element and radioactive gas that is odorless, colorless, tasteless, and completely imperceptible to humans. It forms as part of the natural decay chain of uranium, which is present in varying amounts in rocks and soil throughout the world.

Health risks

Radon is the leading cause of lung cancer for non-smokers — about 21,000 people die from it each year. The risk for lung cancer increases with higher levels of radon and longer periods of exposure.

Radon in homes

Radon gas moves through the ground and enters homes through any opening that connects the living space to the soil. Common pathways are sump basins, cracks in concrete floors and walls, gaps around service pipes, construction joints, and crawl spaces.

Testing is the ONLY way to know your levels

While this map can give an estimate for risk based on tests of other homes and geologic location, testing is the only way to know your specific levels. Radon can vary greatly between two neighboring houses. Fortunately, radon testing is straightforward and relatively inexpensive.

Radon levels

The EPA's action level is 4 pCi/L — the same as Minnesota's average indoor reading. Anywhere above 2 pCi/L, the EPA recommends considering action.
