What Is Radon?
Radon is a naturally occurring radioactive gas that forms as uranium breaks down in soil and rock beneath the ground. Because it has no color, odor, or taste, the only way to determine whether dangerous levels are present is through professional testing.
Radon can enter homes through foundation cracks, utility penetrations, crawl spaces, sump pits, and other openings where the home meets the ground.
Why Is Radon Testing Important?
Since radon cannot be seen or smelled, many homeowners have no idea it’s present until testing is performed.
Long-term exposure to elevated radon levels has been linked to lung cancer, making routine testing an important part of maintaining a healthy home. Even newer homes and well-maintained properties can have elevated radon levels regardless of their age or condition.
