Radon is a naturally occurring, radioactive gas that forms from the decay of uranium in soil, rock, and water. It is a colorless, odorless, and tasteless gas that can infiltrate homes through cracks in the foundation, gaps around pipes, and other entry points. Because it is undetectable by human senses, radon can accumulate in homes without occupants realizing it.

Prolonged exposure to elevated radon levels has been linked to serious health risks, including lung cancer. According to the U.S. Environmental Protection Agency (EPA), radon is the second leading cause of lung cancer in the United States, after smoking. This makes understanding and addressing radon exposure crucial for maintaining a healthy living environment.
