 Radon is a naturally occurring radioactive gas that causes lung cancer after prolonged exposure. It can build to dangerous levels in certain homes. The U.S. EPA and the U.S. Surgeon General recommend that people not be exposed to more than 4 pCi/L of radiation from radon on a long-term basis.
Radon is an odorless, tasteless gas created in the ground where uranium and radium exist. The more uranium found beneath the home, the higher the potential for elevated radon levels within a building constructed upon that soil.
Below are significant data concerning radon levels in the United States and Utah. The figures are presented in pico-Curies per liter (pCi/L). This is a trillionth of a Curie of radiation.
