Radon is a naturally occurring colorless, odorless, radioactive gas found in most soils and rock. It iscaused by the normal decomposition of uranium, releasing radium atoms that emit alpha particles intothe air we breathe. It is everywhere; no state is exempt. Outdoors, the concentration is so nominal thatits impact on human health is negligible. However, in confined quarters, high levels of radon can beproblematic. When we breathe, we inhale the radioactive alpha particles that can then lodge in ourlungs.
