What is Radon Testing?

What is radon?
Radon, an invisible, odorless gas, results from the breakdown of uranium within the earth. The radioactive gas works its way up through the ground and enters homes and offices. The concentration of radon in a home depends on the amount of uranium producing the radon in the underlying rocks and soils as well as the routes available for its passage into the home and the rate of exchange between indoor and outdoor air.

Is it a problem for my family?
The U.S. Surgeon General has advocated for Americans to have their homes checked for radon. "Indoor radon is the second-leading cause of lung cancer in the United States and breathing it over prolonged periods can present a significant health risk to families all over the county," Surgeon General Richard H. Carmona said. The warning estimated that 20,000 Americans die of radon-related lung cancer annually.

How does it get into my home?
Radon gas enters houses through openings such as cracks at concrete floor-wall junctions, gaps in the floor, small pores in hollow-block walls, and also sumps and drains. Consequently, radon levels are usually higher in basements, cellars or other structural areas in contact with soil, and the radon concentrations in houses directly adjacent to each other can be very different.

How do I know if there is radon in my home?
Simple…testing. Cornerstone Inspection Group can test the air quality in your home by monitoring the air you breathe. We will place a monitoring device in the lowest habitable area of your home for a minimum of 48 hours. At that time we will be able to download the data to receive the information about your air quality.

What can I do about excessive levels?
Radon exposure in homes can be easily mitigated during the construction of new homes, but existing buildings can also be protected from radon. Most measures such as increasing under-floor ventilation and sealing cracks and gaps in the floor require simple alterations to the building, but other approaches may have to be taken in areas with high radon concentrations.
