You can’t see it. You can’t smell it. You can’t taste it. Radon, a Class A carcinogen, is the second leading cause of lung cancer, after smoking. Radon comes from the radioactive breakdown of naturally occurring radium found in most Florida soils. As a gas in the soil, it enters buildings through small openings in the foundation. Since the building can hold the radon similarly to smoke trapped under a glass, indoor radon concentrations can increase to many times that of outdoor levels.
