Radon (Rn)

is a naturally occurring, colorless, tasteless, odorless, radioactive gas the comes out of the ground all around and below us.

Radon (Rn)

comes from the natural (radioactive) breakdown of uranium in soil, rock and water and gets into the air.

Radon (Rn)

is ubiquitous. It can get into any type of building, homes, offices, schools, and result in high indoor radon levels.

Radon (Rn)

The US-EPA has determined that high levels of Radon causes lung cancer
more often than second-hand tobacco smoke.
