Facts about Radon:
Radon is a gas. It seeps up through the soil and into homes in Florida. Radon is also found in building materials. This toxin is the 2nd lung cancer cause in all people. The United States, according to the DOH, has pockets of radon beneath the ground in nearly every state. Radon science tells us that radioactive breakdown of radium can occur naturally. In neighborhoods, radon can be found from one house to another. The home next door may have tested elevated for radon and need abatement services, while your home may not. The only way to know is to perform a radon test or radon inspection
Since "it can't be seen, smelled, or tasted" the way to know if your radon readings are high is to test it.
Why risk it? A radon test only takes 48 hours "In the state of Florida, 1 in 5 FL homes have elevated radon levels after radon testing samples were submitted. EPA considers action level of 4 pCi/L." This means radon mitigation is needed to bring downer the radon to safer levels.
