Why is radon data important?
Radon is a naturally occurring radioactive gas that is invisible, odorless, and tasteless. It comes from the radioactive decay of radium, an element found in most rocks and soils. Radon can enter a building from the ground underneath it, and concentrate to tens or even hundreds of times the level in outdoor air.
Radon is the leading cause of lung cancer in non-smokers. That is about 20,000 deaths per year nationwide.
