Radon, a colorless, odorless gas, is the leading cause of lung cancer among non-smokers. Radon can seep into a home from underground and, if left to accumulate, high levels of radon can cause lung cancer. Health officials hope that by increasing public awareness of environmental health risks, such as radon, homeowners will take steps to improve indoor air quality, leading to healthier homes and communities.

January Is Radon Action Month In Minnesota

Gov. Mark Dayton has proclaimed January as Radon Action Month in Minnesota, urging residents to take simple and affordable steps to test their homes for harmful levels of radon gas.

Radon Is a Major Health Risk in Minnesota

MDH estimates that one in three existing Minnesota homes have radon levels that pose a large health risk over many years of exposure. Radon is the second leading cause of lung cancer in the United States and more than 21,000 deaths are attributed to radon each year. Radon exposure, however, is a preventable health threat.

Plan to conduct a radon test in your home, if you haven’t already. As the second leading cause of lung cancer, concentrated radon gas is nothing to ignore.

Has Your Home Been Tested For Radon?

If radon test results indicate that levels in your home are only slightly elevated—less than 4 pCi/L (picocuries per liter of air):

  • Caulk cracks or gaps in the slab, foundation, or framing—wherever your home contacts soil—to inhibit radon gas infiltration. This step also improves the success of other radon reduction strategies.
  • Open exterior crawl space vents to increase air flow and dilute radon buildup.
  • Install a heat recovery ventilator (HRV) also called an air-to-air heat exchanger, can be installed to increase ventilation which will help reduce the radon levels in your home. An HRV will increase ventilation by introducing outdoor air while using the heated or cooled air being exhausted to warm or cool the incoming air. HRVs can be designed to ventilate all or part of your home, although they are more effective in reducing radon levels when used to ventilate only the basement. If properly balanced and maintained, they ensure a constant degree of ventilation throughout the year. HRVs also can improve air quality in homes that have other indoor pollutants. There could be significant increase in the heating and cooling costs with an HRV, but not as great as ventilation without heat recovery.

The filter in an HRV requires periodic cleaning and should be changed twice a year. Replacement filters for an HRV are easily changed and are priced between $10 and $25. Ask your contractor where filters can be purchased. Also, the vent that brings fresh air in from the outside needs to be inspected for leaves and debris. The ventilator should be checked by a Minnesota heating, ventilating, and air conditioning professional to make sure the air flow remains properly balanced.

How Healthy Is Your Home?

Radon Occurrence Maps As stated by the USEPA, “the purpose of this map is to assist National, State, and local organizations to target their resources and to implement radon-resistant building codes. This map is not intended to be used to determine if a home in a given zone should be tested for radon. Homes with elevated levels of radon have been found in all three zones. All homes should be tested regardless of geographic location.”

The EPA has more information about residential radon exposure and what people can do about it in the Consumer’s Guide to Radon Reduction.
