Due North Property Inspection offers radon testing as an add-on service for any home inspection.

If You're Buying A Home in Minnesota, Have It Tested For Radon

The Minnesota Department of Health recommends that every home be tested for radon. The average radon level in Minnesota is more than three times higher than the U.S. radon level, and is considered a serious public health risk. This is due to our geology and how we operate our homes. Minnesota homes are closed up or heated most of the year, which can result in higher levels of radon. In Minnesota, more than two in five homes have radon levels that pose a significant health risk.

What Is Radon & Where Does It Come From?

Radon is a colorless, odorless gas that comes naturally from the soil and can accumulate in the air we breathe. Radon gas decays into fine particles that are radioactive and when inhaled, these fine particles can damage the lungs. Exposure to radon over a long period of time can lead to lung cancer.

Radon is produced from the natural decay of uranium and radium, found in rocks and soil. Uranium breaks down into radium, and radium eventually decays into the gas radon. Radon gas is in the soil and common throughout Minnesota. Because soil is porous, radon moves up from the soil and into the home. It can then accumulate in the air and become a health concern. 

Why It's Smart To Test For Radon During Your Inspection Period

First Reason:  YOUR HEALTH! Radon gas is the number one cause of lung cancer for non-smokers, and the second leading cause of lung cancer in America. Radon testing is recommended by the Minnesota Department of Health and the EPA, among others.

Second Reason: MONEY.  If your radon test results come back with elevated levels of radon, 4.0 pCi/L or higher, a buyer can ask the seller to pay for or install a radon mitigation system. Mitigation systems are generally effective at lowering a homes radon levels, and typically cost less than $1,500. One less expense you need to worry about when moving your family into a new home!

Common pathways for radon to enter your home.

How Radon Enters A Home

Radon levels are very low outdoors, but can accumulate in high concentrations in a home. Factors such as radon levels in your soil, pathways for radon to enter a home, and air pressure differences between outside air and the inside air all play a role in how much radon will be present in a home.


Due North's radon testing services are designed specifically for real estate transactions. Our certified radon tech's use continuous electronic radon monitors to provide quick turn-around, with reports available right after our 48-hour testing window. 


For homeowners who are looking to test their home for radon outside of a real estate transaction, we recommend buying a Do-It-Yourself kit. The Minnesota Department of Health has a great program with AirChek that offers DIY test kits for as low as $9.95, which includes postage, analysis, and a radon test report.
