Radon Information

What is Radon and where does it come from?

Radon is a colorless, odorless, inert radioactive gas that comes from the natural radioactive decay of radium and uranium found in the soil beneath the home. The amount of radon in the air is normally measured in ‘ Pico curies per liter of air’, or pCi/L. There is about 0.35 pCi/L of radon in the outside air we breathe. If the level of radon is equal to or greater than  4 pCi/L, the USEPA recommends that the building or home be mitigated for radon.
