Radon is a naturally occurring, colorless, odorless, tasteless gas. It is formed from the radioactive decay of uranium in the ground (Radon in Drinking Water: Questions and Answers, EPA815-F-99-007, October 1999). A radon fact sheet is available at http://nepis.epa.gov/Exe/ZyPURL.cgi?Dockey=P1008HM1.txt.
