Montana Radon Levels
EPA Radon Levels
Montana has 56 counties and 49 (88%) have been assigned Zone 1 counties by the EPA. Zone 1 counties have the highest potential to have homes test higher than 4 pCi/L. Montana's state radon zone average is 1.13, which is the average of all county zone ratings the EPA has assigned the state, ranking it 4 among all states.
The radon levels in Montana are above average in many areas of the state. As depicted by level map hosted at Montana Department of Health, all but a small handful of counties are prone to elevated radon levels. As such, there’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

Montana Radon Contractor License Information

What are the licensing requirements? There are no state mandated requirements to become a licensed radon contractor in Montana. Those looking for a radon certification can take qualified third party courses that are offered through the NRPP or AARST.
Montana Radon Real Estate Requirements
Does the state of Montana require radon testing for all real estate transactions? No
However both the state of Montana and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though Montana does not require radon testing, we certainly recommend you have a test performed before you purchase a home. If you decide to perform a test after and find elevated levels, there is no reason to panic. Montana radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.

Disclaimer: It is strongly recommended that all households, schools and office spaces test radon levels individually. The EPA Radon Zone data is not an indicator of individual test results, but a guideline for strategic planning. Toxic radon levels can be found in all counties, regardless of their zone rating. While we make efforts to keep this information up to date, it is derived from thirdparty sources which may not be accurate or reflect the most current statistics.
Montana is the 4th most expansive state in terms of size and the 44th most populous. It also happens to be the 48th most densely populated in the entire US.
