Colorado Radon Information

Colorado Radon Program:

Radon Website: Website
Radon Contact: Chrystine Kelley
Active Radon Program: Yes
Require License for Radon Professionals: No

Colorado is the 8th most expansive state and the 22nd most populous. Most Colorado counties have shown moderate to excessive levels of radon.

The state of Colorado also has a very commendable Radon program, with a wide variety of resources and information available on the official site.

After more than 140,000 test results from 2005 through 2012, it has been discovered that the radon levels in the state of Colorado are above average. That means there’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

Colorado Radon Levels

Map of Colorado Radon Levels

Zone 1 (1): Potential for radon levels above 4 pCi/L according to EPA
Zone 2 (2): Potential for radon levels between 2 pCi/L and 4 pCi/L according to the EPA
Zone 3 (3): Lowest EPA level with expected radon levels at or below 2 pCi/L
Disclaimer: It is strongly recommended that all households, schools and office spaces test radon levels individually. The EPA Radon Zone data is not an indicator of individual test results, but a guideline for strategic planning. Toxic radon levels can be found in all counties, regardless of their zone rating. While we make efforts to keep this information up to date, it is derived from third­party sources which may not be accurate or reflect the most current statistics.

Colorado Radon Statistics

Colorado has 63 counties and 51 (81%) have been assigned Zone 1 counties by the EPA. Zone 1 counties have the highest potential to have homes test higher than 4 pCi/L. Colorado's state radon zone average is 1.19, which is the average of all county zone ratings the EPA has assigned the state, ranking it 6 among all states.

Colorado Radon Contractor License Information

Does Colorado require contractors to be licensed? No.

What are the licensing requirements? There are no state mandated requirements to become a licensed radon contractor in Colorado. Those looking for a radon certification can take qualified third party courses that are offered through the NRPP or AARST.

Colorado Radon Real Estate Requirements

Does the state of Colorado require radon testing for all real estate transactions? No

However both the state of Colorado and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though Colorado does not require radon testing, we certainly recommend you have a test performed before you purchase a home. If you decide to perform a test after and find elevated levels, there is no reason to panic. Colorado radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.
