What is Radon?

Radon is a radioactive gas that forms naturally when uranium, thorium, or radium, which are radioactive metals break down in rocks, soil and groundwater. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in buildings and homes. Because radon comes naturally from the earth, people are always exposed to it.

Where does Radon come from?

Radon-222 is the decay product of radium-226. Radon-222 and its parent, radium-226, are part of the long decay chain for uranium-238. Since uranium is essentially ubiquitous (being or seeming to be everywhere at the same time) in the earth's crust, radium-226 and radon-222 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 (picocuries per liter) in air. 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.

Who can I have test my Home?


We would love to be your first choice of being your Radon testing company. We are IAC 2 Certified for Mold, Indoor Air Quality, and Radon testing in GA. Testing is performed in your home for 48 hrs. using a Continuous Radon Monitor (CRM) under closed-door conditions. 12 hours before placement of the device, the homeowner is to close all exterior doors, windows, and garages. When the device is in the house, it is necessary that the house stay "closed" except for momentary entry and exit. This is to get a better snapshot of the home's radon potential. 48 hours after placement, the device is retrieved and results are e-mailed to the homeowner within 12 hours. Will schedule ASAP for due diligence contract needs!

What can I do to eliminate Radon in my home?

Once testing is complete, a professionally designed and installed radon reduction system can bring radon levels back down to a safe number if radon is detected. Many homes’ variables can affect a proper radon mitigation system design as each home is unique and must be viewed this way to ensure the system is adequate to keep the home safe. Schmitt Waterproofing offers custom-tailored radon reduction systems for each home to ensure that any high radon levels will be brought down.

We provide testing for the following counties; Fulton, Henry, Cobb, DeKalb, Gwinnett, Clayton, Douglas, Paulding, Coweta, Rockdale, NewtonSpalding, Butts, and Jasper

Pre-Test Form

Prior to testing, a non-interference agreement form is required. Since the test is so short and results are dependent upon whether the home was kept closed to get accurate measurements, this is necessary to ensure that all parties are aware of what was expected. The form can be found HERE.
