AARST Position Statement
Public Health Risk and Public Policy Concerning Radon Gas
"We must protect the public from lung cancer caused by indoor radon.
Protracted radon exposure increases the risk of all types of lung cancer."
Radon-222 (hereafter called radon) is a colorless, odorless, tasteless, radioactive gas, produced naturally in rocks and soil by the decay of uranium-238 and subsequently radium-226. Radon, with a radioactive half-life of about four days, enters homes and other buildings through cracks and penetrations in the building foundation. Radon gas usually exists at lower concentrations outdoors, but radon is typically present at a higher concentration indoors. A high radon gas concentration in a home or workplace increases the risk of radon-related lung cancer. Radon is the number one cause of lung cancer among individuals who have never smoked, and the second leading cause of lung cancer overall.
DES MOINES, Iowa (AP) - Builders in Iowa would be required to install radon mitigation systems in new homes under legislation that has won approval in an Iowa Senate committee.
The bill moved out of the State Government Committee on Wednesday. Under the proposal, new homes must be built with radon mitigation pipes. If the homeowner discovers radon, they can add a fan to use the system.
Radon is a colorless, odorless gas that can leak through cracks in building foundations. The U.S. Environmental Protection Agency calls radon the second-leading cause of lung cancer in the U.S. The agency also says Iowa's 99 counties are in the agency's highest risk zone for exposure.
A similar bill was approved by the Democratic-majority Senate two years ago but failed to advance in the Republican-controlled House.
