Radon gas is a natural byproduct of uranium that seeps from the ground and to which everyone is exposed – from soil, water, air, and food. Naturally occurring radon within groundwater is volatile and may be released into household air to varying degrees. Theoretically, while radon in the tap water may expose a person to risk of cancer, human studies have not confirmed this. The main concern is over inhalation of radon which has scientifically shown to increase the risk of lung cancer, specifically bronchogenic carcinoma. In that regard, any aerated radon particles from water would add to the already existing airborne radiation in the home.
Lung cancer is one of the most common types of cancer occurring in the United States. The great majority of lung cancer cases occur in people who have been cigarette smokers. It is recognized that lung cancer also occurs as a result of radon exposure. The relationship between radon exposure and lung cancer was established in studies of uranium miners who were exposed to radon as a result of their mining occupation. These individuals had higher rates of lung cancer than expected. It was also known that radon exposed miners who also smoked cigarettes had an even higher rate of lung cancer.
