How does radon gas enter homes?
Radon is a radioactive gas that is formed from the natural decay of uranium. It typically moves up through the ground into the air above and can enter a home through cracks and holes in the foundation and sometimes it may even enter through well water. Your home traps radon gas inside and can build up to high levels. Radon can be a problem in any home, new and old, well-sealed and drafty homes, homes with or without basements. Radon from soil gas is the main problem but in a small number of homes it may come from building material. Radon levels are unpredictable and varies from home to home, even homes next door to each other can have very different radon levels.
