Radon testing is provided as an additional service. Fast, detailed test results are provided at the end of the testing period. Radon is a naturally occurring radioactive gas that can cause lung cancer. Radon gas is inert, colorless, and odorless and is naturally occurring in the atmosphere. Most radon exposure occurs inside homes, schools, and workplaces. Radon gas becomes trapped indoors after it enters through cracks and other holes in the foundation. Indoor radon levels can be controlled and managed with cost-effective techniques. Be sure to add Radon Testing to your home inspection.
