      Bill requiring school testing for radon stalled in Iowa House

      Legislation requiring schools to test for the cancer-causing gas radon appears unlikely to advance in the Iowa House. A subcommittee in the Republican-majority House did not approve the bill Wednesday. Republican Representative Matt Windschitl of Missouri Valley says the cost of mandating radon testing and remediation could boost local property taxes. The Democratic-controlled Senate last month approved the bill. The legislation would require public and private schools to test for the gas and install a system to expel it from buildings. 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 gas exposure.
