Serving Stark County
Radon is a natural radioactive gas that comes up from the soil. You cannot see it, smell it or taste it. The U.S. EPA names radon as the leading cause of lung cancer among non-smokers, and the only way to know a home's level is to test.
A radon test measures the level in the lowest livable area of the home over at least 48 hours. The EPA recommends fixing a home when the result is 4 pCi/L or higher. Dan places the test, picks it up, and gives you the result with a plain explanation of what it means.

Common questions
What does closed-house mean?
Keep windows and outside doors closed, except for normal coming and going, for 12 hours before and during the test. Normal heating and cooling can run.
What if the level is high?
A high level can be fixed. A radon mitigation system, usually a vent pipe and fan, draws the gas from under the home and vents it outside.
My neighbor's house tested low. Do I need to test?
Yes. Radon levels can be very different from one house to the next, even on the same street.
