RADON: Radon is an odorless, radioactive gas resulting from the natural decay of uranium. Uranium occurs in rock (particularly granite), soil and water. The gas is dispersed into the air outdoors but is suctioned into closed buildings and homes the same way air seeps in. It enters a home through concrete and miniscule cracks in foundation floors or walls, through hollow walls and openings around floor drains, pipes and sump pumps. It also enters in the water, particularly a well-water source.
The better insulated the home, the more the radon seeps in, is trapped and builds up to toxic levels. The amount of radon in the soil is determined by the geology under and near the home. Colorado homes are ranked at high risk for radon by the EPA.
Testing for radon is simple and inexpensive. The short term test involves hanging a postcard size envelope in a designated area for 3 to 5 days; then seal and mail. Results are sent to you within a week. Mitigation is recommended if the level is greater than 4. Elevated levels of radon in homes is documented as the number 2 cause of lung cancer. If you don't know the level in your home, we recommend a short term test.
