radon gas
Radon is a radioactive gas that occurs naturally when the uranium in soil and rock breaks down. It is invisible, odorless and tasteless. When radon is released from the ground into the outdoor air, it is diluted and is not a concern. However, in enclosed spaces like homes, it can accumulate to high levels. High radon levels can be a risk to the health of you and your family.
