Boulder County Radon Program

How do you know if you are buying a healthy home?

Educated home buyers ask smart questions: How long has the home been on the market? Are the sellers negotiable?  Has the home been tested for radon? Become an educated home buyer and ask your real estate agent about radon.

For helpful information, download the EPA’s Home Buyer’s and Seller’s Guide to Radon or call 1-800-55-RADON.

What is Radon?

Radon comes from the natural (radioactive) breakdown of uranium in soil, rock, and water. It is an invisible gas that enters buildings from cracks in solid floors or walls, construction joints, gaps in suspended floors and around service pipes, cavities inside walls, and the water supply. Radon can be found in any type of building, but homes are the most concerning, since this is where families spend the most time.

What is the Risk?

When air containing radon gas is breathed in, it attaches itself to the lungs, where it can begin the process of causing lung cancer. Radon is estimated to cause about 21,000 lung cancer deaths per year, according to EPA’s 2003 Assessment of Risks from Radon in Homes.

The only way to know if your home has dangerous levels of radon is to test for it. Once detected, homes with high levels of radon can be easily fixed.
