Radon is a colorless, odorless, tasteless radioactive gas that’s formed during the natural breakdown of uranium in soil, rock, and water. Radon exits the ground and can seep into your home through cracks and holes in the foundation. Radon gas can also contaminate well water.

​Health officials have determined that radon gas is a carcinogen that can cause lung cancer. Studies show that radon is more of a risk to smokers, but nonsmokers have a slightly elevated chance of developing lung cancer when radon levels in the home are high. The only way to find out if your house contains radon gas is to perform radon tests.

Acceptable Radon Levels

The Environmental Protection Agency, EPA, recommends you install a system to reduce radon gas in your home if the level of gas is 4 picocuries of radon per liter (pCi/L) or higher.

Facts About Radon Gas

  • There are no average radon levels for a specific city, state, or region.
  • Houses without basements are as much at risk of radon contamination as houses with basements.
  • It doesn’t matter if your neighbor’s radon test was low or high, results for your home may be completely different.
  • Any Home Can Have High Radon Levels
