RADONSCAN

Radon is a chemical element with symbol Rn. It is a noble gas, colorless, odorless and radioactive occurring mostly naturally as the decay product of radium but also uranium... Because it is a little heavier than air, radon is more likely to settle and cause harm in a building's low, non-ventilated area, such as a basement. Enough radon gas can seeps out of soil into basements and crawl to pose a health risk to homes residents
