Where does radon come from?
Radon is the decay product of radium. Radon and its parent, radium, are part of the long decay chain for uranium. Since uranium is essentially ubiquitous (being or seeming to be everywhere at the same time) in the earth's crust, radium and radon are present in almost all rock and all soil and water.
The amount of radon in the soil depends on soil chemistry, which varies from one house to the next. Radon levels in the soil range from a few hundred to several thousands of pCi/L (pico Curries per Liter). The amount of radon that escapes from the soil to enter the house depends on the weather, soil porosity, soil moisture, and the suction within the house.

Radon Facts
Radon is estimated by the American Lung Association to be the second
leading cause of lung cancer in the U.S. today, causing thousands of deaths
each year. Radon is an invisible, odorless, radioactive gas that has
been found in homes all over the U.S. It comes from the natural breakdown of
uranium in soil, rock, and water, and gets into the air we breathe.
Radon typically moves up through the ground to the air above and into your
home through cracks and other holes in the foundation. Your home can trap
radon inside. Sometimes radon enters the home through well water. Any home
can have a radon problem. This means new and old homes, well-sealed and
drafty homes, and homes with or without basements. In fact, you and your
family are most likely to get your greatest radiation exposure at home. That
is where you spend most of your time. Nearly 1 out of every 15 homes in the
U.S. is estimated to have elevated radon levels.
The EPA and the Surgeon General recommend that you test your home.
Testing is the only way to know if you and your family are at risk from
radon. The EPA and the Surgeon General recommend testing all homes below the
third floor for radon. Contact us today for more information about the radon
testing process
