Should I Test My House For Radon?

July 27th, 2018 by Frank Hough


You may not know it, but radon is the second leading cause of cancer in the United States.  The leading cause of cancer is smoking.

In recent years REALTORs® have been at the forefront of discussions about the dangers of radon gas.  In Minnesota we’ve added a two page document, usually following the sellers disclosure statement, detailing the dangers of radon and how to test for it.

Radon is a poisonous gas that comes up from the earth.  It is estimated to cause about 21,000 lung cancer deaths per year.

The recommended level to mitigate radon gas is anything above four picoCuries per liter of air, or “pCi/L” .

Mitigating radon involves filtering the gas out of the livable space by using a ventilation system that pushes the gas away from the house.  These mitigation systems usually cost between $1,000 and $1,500 to have installed.

Radon testing has become an important part of home inspections.  According to one out of about every fifteen homes in the United States has a radon level that is too high. 

Often times your regular home inspector can test radon levels during your home inspection.  These tests do take some time however, with even the shortest tests often taking 48 hours.  You can also test for radon on your own without using a home inspector but DIY radon tests usually take longer to get results.

Considering that radon is the second leading cause of cancer I hope you’ll take it seriously when moving into your next home.  But if you’re not moving anytime soon and you’ve never tested for radon, it’s not too late.

I would highly recommend at least using a DIY test, or using a professional inspector to test for radon.  You’re going to be in your house for at least a few years, and the results of a radon test could literally be life changing.
