Should I test my home for radon in Minnesota?

Yes, absolutely. Minnesota is Zone 1 (highest risk). The EPA recommends every home be tested, and in Zone 1 states it is especially urgent.

Minnesota Indoor Air Quality Guide

Q: What is the radon level in Minnesota?

Minnesota is EPA Radon Zone 1 with an average of 6.5 pCi/L. Minnesota is entirely Zone 1. Glacial geology and uranium-bearing shale produce very high radon. The state averages the 2nd highest radon readings nationally.

Q: What are the biggest indoor air hazards in Minnesota?

The top concerns are Radon Gas, Carbon Monoxide (CO), Mold Exposure. Extreme cold creates 6+ months of sealed homes. Basements are standard and concentrate radon. Ice dams cause water intrusion and mold. High rates of radon-induced lung cancer.

⚠️ Testing strongly recommended

Minnesota is Zone 1 — the highest risk category. Test every home. If levels are 4 pCi/L or above, install a mitigation system immediately.

Top Indoor Air Hazards in Minnesota

Radon Gas

CRITICAL

Radon is the #2 cause of lung cancer after smoking. It seeps from soil into basements and crawl spaces. You cannot see, smell, or taste it. The only way to know is to test.

Carbon Monoxide (CO)

CRITICAL

CO is a silent killer — colorless, odorless, and lethal at high concentrations. It binds to hemoglobin 200x more than oxygen. Every home with fuel-burning appliances needs a CO detector.

Mold Exposure

HIGH RISK

Mold releases spores that trigger allergies, asthma attacks, and respiratory infections. Black mold (Stachybotrys chartarum) produces mycotoxins linked to neurological symptoms.
