As you can see above, Rockingham County is in Zone 1 -- which means we are in an area that is likely to have high radon levels. 

What is radon, and what does it mean for you?  Read on, from the EPA....

Radon is a radioactive gas that comes from the natural breakdown of uranium in soil, rock and water and gets into the air you breathe. Radon typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Radon can also enter your home through well water. Your home can trap radon inside.

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 United States is estimated to have an elevated radon level (4 pCi/L or more).

If you are buying a home with a basement, I would recommend that you consider a radon test as a part of your home inspection process.
