Radon is a naturally occurring colorless, odorless, radioactive gas that causes lung cancer. Radon enters the home, workplaces or schools through cracks, seams, or other holes in the foundation. Radon gas then gets trapped indoors, which increases your risk for lung cancer over time. The EPA has estimated that 21,000 lung cancer deaths from radon exposure happen each year, and is the second leading cause of lung cancer in the United States. Testing is the only way to know if your home or business is at risk for radon exposure. The EPA recommends mitigation if the radon levels are 4.0 pCi/L or higher. Radon levels can be managed with a proven, cost effect radon mitigation system that we design to each structure. The EPA recommends retesting structure every two years, even if you have a mitigation system installed.
