Why Radon Testing Matters in Billings
Radon is a naturally occurring radioactive gas produced by the decay of uranium found in soil and rock beneath your home. It enters through foundation cracks, construction joints, gaps around pipes, and any opening where the building meets the ground. In Billings and throughout Yellowstone County, the geological composition of the soil creates conditions where radon concentrations frequently exceed safe thresholds. The EPA classifies much of Montana as Zone 1 for radon risk, meaning predicted average indoor screening levels exceed 4 pCi/L, the federal action level.
Radon is completely invisible, odorless, and tasteless, which makes professional testing the only reliable way to determine if your home has elevated levels. It is the second leading cause of lung cancer in the United States, responsible for an estimated 21,000 deaths each year. Testing is straightforward, affordable, and could protect your family's health for years to come.
Types of Radon Tests We Offer
Short-term radon tests run for 2 to 7 days and provide a quick snapshot of radon concentrations in your home. These tests are ideal for real estate transactions, initial screenings, and situations where fast results are needed. Our short-term testing uses continuous radon monitors (CRMs) that record hourly measurements, delivering detailed data about how levels fluctuate throughout the test period.
Long-term radon tests run for 90 days or more and provide a more accurate picture of your home's year-round average radon exposure. We recommend long-term testing whenever time permits, because radon levels fluctuate with weather patterns, soil moisture, barometric pressure, and seasonal changes common across the Billings area. For the most comprehensive understanding of your exposure, continuous monitoring devices can track radon levels in real time and alert you to any spikes.
Understanding Your Results
After testing is complete, our licensed technicians analyze the data and provide a detailed report showing your home's radon concentration measured in picocuries per liter (pCi/L). If your results fall below 2 pCi/L, your home is within acceptable levels, though we recommend retesting every two years since conditions can change. Results between 2 and 4 pCi/L fall in a range where the EPA suggests considering mitigation, as there is no known safe level of radon exposure.
For results at or above the EPA action level of 4 pCi/L, we strongly recommend installing a radon mitigation system as soon as possible. Our team can discuss mitigation options immediately after testing and often schedule installation within days. We also offer bundled pricing when you combine testing with mitigation, applying the cost of your test toward the total project price.
