Quick Facts...
- Radon is a colorless, odorless, radioactive gas that can enter the home.
- Most of Colorado contains high concentrations of radon, considered the second highest cause of lung cancer.
- All Colorado homes should be tested for radon.
- Radon reduction methods can be planned for and installed during new home construction.
- Home buyers and renters should ask if the home has been tested for radon and for the results.
What is Radon?
Radon is emitted from uranium, a naturally occurring mineral in rocks and soil. Normally, radon rises up through the soil and dissipates in the air outside. Radon becomes a concern, however, when it seeps through openings such as cracks, loose fitting pipes, sump pits, dirt floors, slab joints or block walls and accumulates in the home. See Figure 1.
Air pressure inside the home is usually lower than pressure in the soil around the house’s foundation. Because of this difference, the house acts like a vacuum, drawing radon in through foundation cracks and other openings.
Every home should be tested for Radon. San Juan Basin Health offers Community Presentations on Radon awareness, testing and mitigation each year. Individuals attending the presentation receive free radon test kits. Click here for a current schedule of workshops.

Radon has been identified as a risk factor in developing lung cancer because it decays into radioactive particles that can get trapped in the lungs. These particles release bursts of energy that damages lung tissue. It is estimated that radon may be associated with about 21,000 lung cancer deaths per year in the United States, second only to smoking.
