What is Radon?
Radon is a colorless, odorless, radioactive gas. It forms naturally from the decay (breaking down) of radioactive elements, such as uranium, which are found in different amounts in soil and rock throughout the world. Radon gas in the soil and rock can move into the air and into underground water and surface water. Radon is present outdoors and indoors. It is normally found at very low levels in outdoor air and in drinking water from rivers and lakes. It can be found at higher levels in the air in houses and other buildings, as well as in water from underground sources, such as well water. Radon breaks down into solid radioactive elements called radon progeny (such as polonium-218, polonium-214, and lead-214). Radon progeny can attach to dust and other particles and can be breathed into the lungs. As radon and radon progeny in the air break down, they give off radiation that can damage the DNA inside the body’s cells.
What can I do to make my home safer?
Radon Mitigation is defined as any process used to reduce radon gas concentrations in the breathing zones of occupied buildings or radon from water supplies. Mitigation of radon in the air is accomplished through ventilation, either collected below a concrete floor slab or membrane on the ground, or by increasing the air changes per hour in the building. Treatment systems using aeration or activated charcoal are available to remove radon from domestic water supplies.

Deml Heating and Air Conditioning is certified to perform radon testing and, if necessary, radon mitigiation. We can help you reduce your levels with as little disruption as possible to the outside aesthetics of your home.
Steele County Radon Levels
"...According to data from the Minnesota Department of Health, high levels of radon — an odorless, tasteless and invisible gas that has been known to cause lung cancer — are present in 67 percent of the homes in Steele County. Two-thirds of the homes in Steele County have levels of at least 4 picocuries per liter. A picocurie is one-trillionth of a curie, an international unit of measurement for radioactivity. Dan Tranter, supervisor of the Indoor Air Unit at the state’s health department, said radon poses a risk to those living in high concentrations..." - Owatonna People's Press 8/19/2013
