Radon is a naturally occurring radioactive gas that is found in the environment. It is produced by the breakdown of uranium in soil, rock, and water. Radon is odorless, colorless, and tasteless, and can be found in the air we breathe. In Knoxville, Iowa, radon has been a concern since the early 1980s.
In the early 1980s, the Iowa Department of Public Health began testing for radon in homes and businesses in Knoxville. The results of these tests showed that radon levels in the area were higher than the Environmental Protection Agency’s (EPA) recommended levels. This prompted the EPA to declare Knoxville a “radon-affected area” in 1984.
Since then, the EPA has worked with the Iowa Department of Public Health to reduce radon levels in Knoxville. The EPA has implemented a number of measures to reduce radon levels, including the installation of radon mitigation systems in homes and businesses, and the promotion of radon testing and awareness. In addition, the EPA has conducted research to better understand the sources of radon in Knoxville.
Today, radon levels in Knoxville are much lower than they were in the 1980s. The EPA continues to monitor radon levels in the area and encourages residents to test their homes for radon. By taking these steps, Knoxville residents can help protect their health and the health of their families.
