Radon is a colorless, odorless, radioactive gas emitted from uranium, a naturally occurring mineral in rocks and soil. Normally, radon rises up through the soil and then dissipates in the air outside. Radon becomes a concern, however, when it seeps in through openings such as cracks, loose-fitting pipes, sump pits, dirt floors, slab joints, or block walls and accumulates in the home.
This publication will help householders understand radon — what it is, its effect on heatlh, how to test for it, and some remodeling or new building techniques that can reduce radon levels in the home.
