January is National Radon Action Month – JCPH offering free test kits by mail to Jeffco residents

National Radon Action Month

Jefferson County, Colo. – January is National Radon Action Month, and Jefferson County Public Health (JCPH) is encouraging residents to protect themselves and loved ones from dangerous radon gas by testing their homes. To help, JCPH is offering 875 free radon test kits during the month of January, while supplies last, one per address and on a first come-first served basis, to Jefferson County residents. 

Due to the outstanding circumstances of the COVID-19 pandemic, for the first time, JCPH will be mailing the test kits to residents. To sign up to receive your kit, please visit and fill out the form in its entirety. Kits will be mailed once per week. JCPH will only be able to provide one kit per request/address, so if you are requesting on behalf of an HOA or larger organization, please send this link to your residents and ask them to request their kit individually. 

Radon is a dangerous and naturally-occurring radioactive gas that you cannot smell, taste or see. People are exposed to radon primarily from breathing radon in air that enters homes and other buildings through cracks and gaps in foundations.

Radon exposure is the leading cause of lung cancer among non-smokers and a top environmental cause of cancer nationwide. In Jefferson County, more than half of homes tested have high levels of radon. While there is always some radon in the air, high levels of exposure to radon over time can lead to a significant risk of developing lung cancer. The risk of lung cancer is even greater for smokers who are exposed to radon.

“We know that in Jeffco, it doesn’t matter if your home is new or old, or large or small – any home can have high levels of radon. The geology here in Colorado makes us more prone to radon, but by testing, you can know if you need to take steps to make your home safer for you and your family,” said Mitch Brown, Environmental Health Supervisor at JCPH. “If we can find the places radon is getting trapped indoors, we can mitigate it and lessen the negative health effects it has on our community. That’s a win for us all.”

Homeowners do not need to test for radon annually if their homes have recently tested below the maximum threshold (4 picocuries per liter). If your home has recently tested below this, plan on testing every 2-3 years. If your home has tested above this threshold, more comprehensive testing may be needed to gauge the severity of the problem. There is no safe level of radon, so even if your home tests below 4 picocuries per liter, you may still want to consider mitigation.

In addition to providing the free test kits, JCPH staff will be available to help homeowners understand how to use the test kits properly and what to do if the test results show high levels of radon in the air. If action is needed to reduce radon in a home, it’s important to test homes for radon again to be sure the action worked and the air is safe. Resources may be available for those whose homes test positive for high levels of radon and who qualify through the Colorado Department of Public Health and Environment.

Testing your home, and installing proper air quality controls if high levels of radon exist, is an effective way to prevent the harmful effects radon can have on you and your family. After January and throughout the remainder of 2021, radon test kits will be available for purchase at JCPH for $10 each.
