North Dakota Indoor Air Quality Guide

Q: What is the radon level in North Dakota?

North Dakota is EPA Radon Zone 1 with an average of 8.4 pCi/L. North Dakota has the 2nd highest radon levels in the US. The entire state is Zone 1. Glacial deposits over uranium-bearing Pierre Shale create extreme readings.

Q: What are the biggest indoor air hazards in North Dakota?

The top concerns are Radon Gas, Carbon Monoxide (CO), Poor Ventilation (Stale Air). Extreme cold with 7+ months of sealed homes concentrates radon to dangerous levels. Many homes have basements that further concentrate gas. Low population means limited testing and mitigation infrastructure.

North Dakota has the 2nd highest radon levels in the US. The entire state is Zone 1. Glacial deposits over uranium-bearing Pierre Shale create extreme readings.

⚠️ Testing strongly recommended

North Dakota 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 North Dakota

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.

Poor Ventilation (Stale Air)

MODERATE

Modern energy-efficient homes trap pollutants indoors. Without adequate ventilation, CO2, VOCs, and airborne pathogens accumulate to levels 2-5x higher than outdoors. This is called sick building syndrome.
