Radon is a naturally-occurring radioactive gas that is a decay product of radium. It dissolves in ground- and well-water and can be released into the air during water use. It can also enter a home by rising through the earth up through foundations. It is widely present throughout Maine, affecting as many as one in three homes (Bangor Daily News, 2014).
Radon has been linked to lung cancer.
