Indoor Air Quality: Radon

Radon is a naturally occurring radioactive gas, that means it continuously decays and releases radiation. It is produced from minerals in soil, such as uranium and radium. It is colorless, odorless and tasteless.  Long-term exposure to radon can lead to lung cancer. In fact, over 20,000 lung deaths each year are from radon, making it a serious health concern for all Minnesotans.   Free Radon Tests are available at Kandiyoh County Public Health.  Pick up your free Radon Test at Kandiyohi County Public Health, 2200 23rd Street Northeast, Suite 1080, Willmar, MN  56201. (Kandiyohi County Health and Human Services Building)
