To meet the requirements set forth in the Code of Colorado Regulation, 6 CCR 1010-6, initial District-wide radon testing was performed in 1991. However, the regulation requires that all building additions and remodels constructed after the initial testing be re-tested for radon.
Radon is a cancer-causing radioactive gas. You cannot see, smell or taste radon. The Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. If you smoke and you are exposed to high radon levels, you’re at high risk for developing lung cancer. Some scientific studies of radon exposure indicate that children may be more sensitive to radon. This may be due to their higher respiration rate and their rapidly dividing cells, which may be more vulnerable to radiation damage.
Testing is the only way to determine whether or not the radon concentration in a school room is below the action level. Testing is only performed in frequently occupied rooms including classrooms, offices, labs, cafeterias, libraries, auditoriums and gymnasiums on the ground level.
EPA recommends that schools take action to reduce the level of radon when levels are 4 pCi/L (or 0.02 WL) or higher. Below are the results from radon testing conducted in past years. If any samples are higher than 4 pCi/L, we will follow up with additional testing and will post those results.
