What is Radon?

Updated: Feb 24, 2021

Radon is a radioactive gas that has been found in homes, schools and buildings around the world. Radon comes from the natural breakdown of uranium in soil and rock, and moves up into the indoor air that people breathe. Radon is the leading cause of lung cancer in non-smokers. Radon mitigation systems reduce radon levels in homes and buildings. Inspection of these systems helps assure that they were installed properly and are performing as designed. If the radon level is 4 picoCuries per liter (pCi/L) or higher then correction is recommended and if Radon levels are less than 4 pCi/L it can still pose a risk, but can be reduced.

In most cases, a system with a vent pipe and fan is used to reduce radon. These "sub-slab depressurization" systems do not require major changes to your home. Similar systems can also be installed in homes with crawlspaces. These systems prevent radon gas from entering the home from below the concrete floor and from outside the foundation
