Radon: Fact or Fiction?

Did you know radon is present in many Idaho homes? The Idaho Environmental Health Program within the Division of Public Health manages the Idaho Radon Program. Below is information to separate radon facts from fiction and help keep your family healthy.

FACT: All homes should be tested for radon.

Radon is a naturally-occurring radioactive gas that you cannot see, smell, or taste. It enters homes through gaps or cracks in the foundation. All homes, including new builds, existing homes, and those with and without basements, can have high levels of radon gas. With more people working from home due to the COVID-19 pandemic, the risk of radon exposure may be increased as more time is spent within the home. 

Testing is easy and is the only way to know if you are being exposed to radon in your home. The Environmental Protection Agency (EPA) recommends testing your home every two years or after any remodeling.

 You can order a FREE short-term test kit from www.radonidaho.org or call the Idaho Careline at 2-1-1 or 1-800-247-2435.

FICTION: Radon is not an issue where I live.

Two out of every five homes tested in Idaho have higher than the recommended levels for radon. In fact, high radon levels have been found in every county in the state. To learn more about radon test results and recommended actions, visit www.radonidaho.org.  You can also view Idaho radon test results by zip code on an interactive map and order a FREE short-term test kit.

FICTION: Radon is not harmful to my health.

Long-term exposure to radon gas is known to cause lung cancer and is the leading cause of lung cancer in non-smokers. To learn more about the health effects of radon, visit the Environmental Protection Agency’s (EPA) Health Risk of Radon website at epa.gov/radon/health-risk-radon.

FACT: Winter is the best time to test a home for radon.

Radon levels can change by season and with the weather. The highest levels of radon are found during the winter months when homes get less fresh air. To learn more about radon testing and how to respond to a radon problem, visit www.radonidaho.org.

FACT: A radon problem can be solved!

Radon mitigation systems can effectively reduce the levels of radon in a home. The Idaho Radon Program recommends hiring a nationally-certified radon professional to fix your home. To locate a radon professional, visit www.radonidaho.org.   

The Idaho Radon Program is offering a free two-hour interactive radon workshop that will explain what radon is, how it enters your home, and what you can do to help prevent excessive exposure and reduce your risk of lung cancer.  To register, please visit www.radonidaho.org.
