What level of radon is dangerous?

The EPA recommends mitigation at 4 pCi/L or higher. Between 2 and 4 pCi/L, you should consider mitigation — long-term exposure at this range still carries lung-cancer risk. Below 2 pCi/L, the EPA suggests retesting every two years.

How much does radon mitigation cost in Colorado?

A standard sub-slab depressurization system in Colorado typically runs $1,200–$2,500, depending on home size, foundation type, and venting path. That single system reduces indoor radon by 95% or more in the majority of homes. Crawlspace installs cost more ($2,000–$5,000) because the membrane and tie-ins are more involved.

Why are radon levels elevated in Morgan County?

Geology drives most of it. Granitic bedrock and uranium-bearing soils — common across Colorado — release radon as they decay, and Front Range building style (basements, tight envelopes, forced-air systems) concentrates that gas indoors. Higher-elevation counties also tend to have lower atmospheric pressure, which can pull radon up through the foundation more aggressively.

In Morgan County, Colorado, 64.2% of pre-mitigation home radon tests came back at or above the EPA action level of 4 pCi/L — based on 310 tests collected by the Colorado Department of Public Health and Environment between 2005 and 2024. The county’s median pre-mitigation reading was 5.1 pCi/L, with a maximum recorded result of 236 pCi/L.

EPA recommends mitigation when long-term indoor radon measures at or above 4 pCi/L. Counties with elevated medians and large test counts — like Morgan — typically warrant testing during real-estate transactions and seasonal retesting in occupied homes.
