Radon TESTING

Radon is an odorless radioactive gas that results from the natural breakdown of uranium in the soil. Uranium is present in most of the soil and rock around the world. It is typically concentrated in areas with lots of granite, shale, phosphate, and pitchblende.

The gas is a deadly carcinogen. It emits radioactive particles that can be inhaled into the lungs. The adverse health effect—lung cancer—may not be produced immediately.
