Radon Control Products
Radon gas is created when uranium in the soil decays. The gas then seeps through any access point into a home. The common entry points are cracks in the foundation, poorly sealed pipes, drainage or any other loose point. Once in the home, the gas can collect in certain areas - especially basements and other low-lying, closed areas - and build up over time to dangerous levels.
The Environmental Protection Agency of the US Government has set a threshold of 4 pico curies per liter as the safe level. As humans are exposed to the gas over a period of years, it can have a significant and detrimental effect.
Radon has been found in homes in all 50 of our states. Certain areas are more susceptible than others (http://www.epa.gov/radon/zonemap.html), but no location is immune. Concentrations of radon-causing materials in the soil can be either natural or man-made. Homes built near historic mining operations may be at higher risk.
