The gas escapes from the ground through cracks and other holes in your home’s foundation. Your home traps the gas and with time, it builds up in plenty and can have adverse effects on those breathing it. Radon gas is said to decay into radioactive particles that can get trapped in the lungs leading to lung tissue damage and potential lung cancer. Colorado is known as Zone 1 when it comes to the presence of high radon gas levels. Nearly 73% (that is every 3 out of 4 homes) of all homes in Colorado have high levels of the gas. The EPA recommended action level is 4 pCi (picocuries) of radon per one liter of air, meaning that any level higher than that requires mitigation. Here are several counties in Colorado with the highest radon levels and reasons why they have plenty of it; Zone 1 counties (62) These are the counties that bear the highest recorded average radon levels. Particularly, the Pikes Peak region is the most affected area within Colorado as it has high levels of … Continue reading What counties in Colorado tend to have high radon readings?
