What is Radon?
Radon is a naturally occurring colorless, odorless, radioactive gas found in most soils and rock. It is caused by the normal decomposition of uranium, releasing radium atoms that emit alpha particles into the air we breathe. It is everywhere; no state is exempt. Outdoors, the concentration is so nominal that its impact on human health is negligible. However, in confined quarters, high levels of radon can be problematic. When we breathe, we inhale the radioactive alpha particles that can then lodge in our lungs.
Radon is the number one cause of lung cancer among non-smokers in the United States, according to Environmental Protection Agency (EPA) estimates. 1 of every 15 homes is estimated to have radon levels at or above the maximum safety level of 4.0 pCi/L.
