Radon is a radioactive gas that is colorless, odorless, and tasteless. The EPA estimates that Radon causes about 21,000 deaths per year, it is the second highest cause of lung cancer.
Radon is a naturally existing gas that is formed by the natural decay of uranium in rock, soil, and water. It occurs widely in the Earth’s crust and can be found in all 50 states. The EPA estimates that nearly one in every 15 homes has elevated radon levels.
If you are buying or selling a home, you can and should test for radon. It’s just like getting a Home Inspection or testing for termite’s. The test consists of testing the quality of the air for at least a 24 hour period, sometimes longer. Higher than 4 pCi/L and you should have radon mitigation. It’s a pretty easy fix and, considering the other possibilities, isn’t too expensive. Currently mitigation costs around $1000-$1800, depending on the size of the home, design of the home, foundation, construction material, and the local climate.
A Radon Mitigation system consists of ASD – Active Soil Depressurization. The system draws radon gas from beneath the foundation of the home and exhausts it outside before it can enter the home. It consists of a plastic pipe that is connected to the soil through a hole in a sump pump lid, or beneath a plastic sheet in a crawl space. The pipe is then attached to a quiet, continuously operating fan that discharges the radon outside.
