Now is a good time to check the radon levels in your home. Your home is likely sealed up for the colder winter temperatures outside, so radon levels may be their highest now.

Each year, about 21,000 lung cancer deaths are attributed to excessive radon exposure. Radon is colorless and odorless. It comes from the natural decay of uranium found in nearly all soils.

Radon can move up through the ground and into your home through cracks and other holes in the foundation. Your home can trap radon inside, where it can build up. Any home — new or old, well-sealed or drafty, with or without a basement — may have a radon problem.
