Radon is a colorless, odorless, tasteless, chemically inert radioactive gas. Radon is formed by the natural radioactive decay of uranium in rock, soil and water. It is a natural part of our environment and can be found in all 50 states. In the majority of radon problems in the US and Florida, radon moving through the ground enters into our homes via cracks, gaps and openings in floors and walls. With the recent adoption of energy efficient all concrete construction in multifamily buildings, elevated radon levels have resulted from the small amount of radon emanating from building construction materials.

Because most people spend up to 90 percent of their time indoors, indoor exposure to radon is an important concern. According to the Surgeon General, radon is second only to smoking as the leading cause of lung cancer. The USEPA states that any radon exposure carries some risk and no level of radon exposure is always safe. However, the USEPA recommends homes be fixed if an occupant's long-term exposure will average 4 picocuries per liter (pCi/L) or higher. In Florida, state statutes authorize the Department of Health to establish state standards for radiation exposure in buildings. Florida Administrative Code 64E-5.1001 states that th eannual average radon decay product concentration in Florida Buildings shall not exceed 0.02 working levels including background. According to the Florida Department of Health, 1 out of every 5 homes in our state has elevated radon levels. Unless you test for it, there is no way of telling if or how much is present in your home.

When installed properly, radon-resistant construction techniques can greatly reduce the risk of developing lung cancer from exposures to radon in the home. There are several proven methods for reducing radon in your home. For an excellent discussion about Florida standards for radon-resistant construction standards, CLICK HERE.

In Florida, individuals and businesses providing radon services or any other radon related activity must be certified. For more information about the certification and their requirements, please CLICK HERE.
