Radon is radioactive gas that is colorless and odorless. It is produced by decaying uranium and found in all soils. When this gas enters your home and gets trapped, it can begin to cause problems. Prolonged exposure to radon can cause lung cancer.
So, how does it get into your house? The radon gas moves from soil into your home and can seep through pores in the concrete. The worst points of entry include gaps in the walls and floors. It can also come in through gaps around pipes and wires, crawl spaces, and openings around the sump pump.
