Building Radon Out
Radon is a naturally occurring, colorless, odorless gas that comes from the soil of the earth. It’s a radioactive noble gas that is formed from the decay of radium. Homes can have high concentrations of Radon, creating a unhealthy air quality. In fact it’s the the number 2 cause of lung cancer in the U.S. If your thinking about new construction plan in installing a Radon mitigation system. It’s relatively inexpensive and easy to do. I’ve discovered a great resource on the EPA website about Building Radon Out [ PDF 5.5 MB], a how-to for contractors or DIY’s. Though I didn’t see a section on earthen floors and radon mitigation it does cover other types of flooring systems.
