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.

The American Association of Radon Scientists and Technologists (AARST), has released four American National Standards for radon measurement and mitigation that will greatly enhance radon risk reduction in the United States. These new standards will be available for shipping on February 1, 2014 at www.aarst.org/bookstore.shtml
The new ANSI-approved standards were developed by the AARST Consortium on National Radon Standards, and include advances in consensus standards for mitigating radon in multi-family housing, and in large buildings and schools, as well as standards for measuring radon in single family homes and in large buildings and schools.
Gary Hodgden, Chair of the AARST National Radon Standards Consortium Executive Stakeholders Committee, announced that the four standards approved through the ANSI accredited process include:
