Indoor Environment

The Idaho Indoor Environment Program offers information and assistance to educate communities throughout Idaho about indoor air pollutants including radon, mold, carbon monoxide, and lead. This is achieved through making presentations to groups such as Realtors, county and city building officials, schools, and answering the public's phone calls. Educational materials and programs are offered through local community events, television and radio. Educational materials about radon are provided free to the public to increase awareness about the danger of high radon levels and ways to reduce exposure.

  • Radon - Radon is a colorless, odorless, tasteless, naturally occurring radioactive gas that comes from the breakdown of uranium found in most rocks and soil. For more information, see Radon Fact Sheet.
  • Mold - Mold is a type of fungus that grows on plants and fibers and is most often associated with damp, musty areas such as bathrooms, basements, and attics. For more information, see Mold Fact Sheet.
  • Carbon Monoxide - Carbon monoxide is an odorless, colorless, tasteless, poisonous gas that occurs from incomplete burning of natural gas and other materials containing carbon such as gasoline, kerosene, oil, propane, coal, or wood. For more information, see Carbon Monoxide Fact Sheet.
  • Lead -Lead is a highly toxic heavy metal that was used in many products such as paint, gasoline, and plumbing. For more information, see Lead Fact Sheet.
