Radon can be found in any home, under any circumstances. It's an invisible radioactive gas that has no taste, smell or color. Over time, the uranium in rocks and soil decays and radon gas is released, which gas lets off radioactive particles. Because radon is a gas, it can enter buildings through openings or cracks in the foundation. Radon decays quickly, giving off tiny radioactive particles. When inhaled, these radioactive particles can damage the cells that line the lung. Long-term exposure to radon can lead to lung cancer, the only cancer proven to be associated with inhaling radon. According to the EPA and the American Cancer Institute, radon gas
