Where Does Radon Come From?

Radon, the natural breakdown of uranium in rock and soil, is a radioactive Class A carcinogen proven to cause lung cancer as a result of it’s decay products. When radon breaks down or decays, they emit alpha particles. In addition, radon has a relatively short half life of 3.8 days. Radon gas can move through the soil quickly and hence into one’s home and breathing space. Radon is inert however it is when radon breaks down into radon decay products that presents the greatest human health risk. If radon concentrations are elevated in a home, the amount of radon inhaled is also elevated. If radon is not exhaled before the 3.8 day half life expires, radon will start the decay process in the lungs releasing it’s radioactivity.
