Radon is a silent, invisible threat affecting homes across the U.S.; Southeast Idaho is no exception. Many areas of Idaho have elevated radon levels that exceed the Environmental Protection Agency's recommended action level. If you're buying a home, selling one, or have never tested for radon before, this article explains what you need to know and how Vantage Point Inspections can help.
What Is Radon and Why Should You Care?
Radon is a naturally occurring radioactive gas that forms when uranium in soil, rock, and water breaks down. It seeps into homes through cracks in foundations, crawlspaces, sump pumps, and other openings. Because it's colorless and odorless, you won't know it's there without proper testing.
According to the EPA, radon is the second leading cause of lung cancer in the United States. Long-term exposure to elevated levels can be deadly, especially for children and smokers.
Is Southeast Idaho at Risk for High Radon Levels?
Yes. Several counties in Southeast Idaho—including Bonneville, Bingham, and Bannock—have been classified as Zone 1 by the EPA, meaning they have a predicted average indoor radon screening level greater than 4.0 pCi/L. This is the level at which the EPA recommends taking corrective action.
Given the geology of Southeast Idaho and the prevalence of basements and crawl spaces in local homes, radon is a significant concern for residents throughout the region.
Common High-Risk Areas Include:
Idaho Falls
Pocatello
Blackfoot
Ammon
Rigby
How Do You Test for Radon?
Testing for radon is simple, affordable, and essential. At Vantage Point Inspections, we offer professional radon testing services that provide accurate, same-day results using calibrated equipment.
There are two main types of radon tests:
Short-term tests (2–7 days): Best for real estate transactions or quick screenings.
Long-term tests (90+ days): Provide a more accurate year-round average.
Our inspectors are trained to perform both types and interpret the results in context with your home's design and location.
What If Your Home Has High Radon Levels?
If your home tests above 4.0 pCi/L, don’t panic. Radon mitigation systems are highly effective and relatively inexpensive compared to the health risks of doing nothing.
Mitigation options may include:
Sub-slab depressurization (the most common method)
Sealing cracks and openings
Improving home ventilation
We work with trusted local radon mitigation contractors and can guide you through the process following your home inspection.
Protect Your Home and Family with Radon Testing
Whether you're buying a home in Idaho Falls or have lived in Pocatello for years, radon testing should be part of your home maintenance routine. It’s an easy way to protect your family’s long-term health and give you peace of mind.
