What is Radon?

Radon is a cancer-causing, radioactive gas produced from the breakdown of uranium in soil, rock, and water. You can’t see, smell, or taste radon — but it can accumulate in your home, creating serious health risks. According to the Surgeon General, radon is the second leading cause of lung cancer in the United States, second only to smoking.

Why Should I Test for Radon?

Testing is the only way to know if your home has radon. The EPA and Surgeon General recommend testing all homes below the third floor. Radon testing is quick, affordable, and can prevent life-threatening health risks. Colorado’s geology makes the Denver Metro and Front Range particularly vulnerable to high radon levels.

What are the Health Risks of Radon?

• Radon exposure is estimated to cause thousands of lung cancer deaths each year.
• Smokers exposed to radon face an especially high risk of lung cancer.
• Long-term exposure, even at moderate levels, can damage lung tissue over time.

How Does Radon Enter a Home?

Radon typically moves up through the soil into homes through cracks in the foundation, construction joints, gaps, sump pumps, and service pipe openings. Any home can have high radon levels — whether new or old, basement or slab-on-grade.

Can Radon Problems Be Fixed?

Yes. Radon mitigation systems are highly effective and can reduce radon levels by up to 99%. Even very high levels can be lowered to safe thresholds. New homes in Denver and surrounding areas can be built with radon-resistant features, but every property should still be tested after completion.
