Boulder County Public Health staff and the Board of County Commissioners proclaimed January 2025 as National Radon Action Month for the county at the Jan. 7 meeting.

Patricia (Patty) Dooley Stapelli, an environmental health specialist with Boulder County Public Health, introduced the proclamation and urged residents to test their homes for radon, noting that the average person spends most of their time indoors and that Colorado’s geology produces elevated radon potential in many areas. The proclamation cites the U.S. Environmental Protection Agency’s designation of the Colorado Rocky Mountain region as Zone 1 for radon potential and notes that testing is “simple and inexpensive” and that identified radon problems can be fixed.

The board adopted the proclamation to encourage testing, remediation where levels exceed the EPA action level of 4 picocuries per liter, and radon‑resistant construction practices for new homes.

Ending: The proclamation places county public health messaging behind radon testing and remediation in January 2025 and directs staff to continue outreach about radon testing and mitigation resources.
