Radon is a naturally-occurring radioactive gas that may cause cancer, and may be found in drinking water and indoor air. Some people who are exposed to radon in drinking water may have increased risk of getting cancer over the course of their lifetime, especially lung cancer.
One method for removing radon from water is a granular activated carbon (GAC) unit. GAC units are constructed of a fiberglass tank containing granular activated carbon—a fine material that traps and holds the radon. The carbon may also need to be replaced annually to reduce the hazard of accumulated radioactivity. Spent GAC filters used for radon removal may need special disposal.
