Radon is a naturally occurring colorless, odorless, and tasteless radioactive gas that is caused by the breakdown (radioactive decay) of uranium in the earth's soil. Radon gas migrates through the soil and into our homes at all times. Radon presents a health risk when unacceptable levels are found in our homes and are inhaled for prolonged periods. The EPA and the Surgeon General recommend testing all homes for radon.	215-968-1933 Tri-County's Radon Lab Partner
