Radon Testing for Multifamily Properties, Schools, and Large Buildings
Why test for radon?
Radon is a naturally occurring radioactive gas that enters buildings through cracks and openings in the foundation. It is odorless, colorless, and invisible—but long-term exposure can cause serious health risks. In fact, radon is the second leading cause of lung cancer in the United States, according to the EPA.
Multifamily buildings, schools, and large commercial structures are particularly vulnerable due to their size, complexity, and high occupancy. In Montana, radon levels are commonly elevated, and while there is no statewide mandate requiring testing in these settings, building owners and administrators remain responsible for providing a safe indoor environment.

Testing Standards and Protocols
Safe Home Environmental follows national standards established by the American Association of Radon Scientists and Technologists (AARST). These include:
These protocols define the correct number and placement of monitors, required test durations, and procedures to ensure accuracy. Testing is performed under closed-building conditions, typically during colder months when radon levels tend to be highest.
The Advantages of Using Continuous Radon Monitors (CRMs)
Continuous Radon Monitors are the most effective tools for testing in large or complex buildings. Compared to passive devices, CRMs offer several key advantages:
Using CRMs is especially important when testing multiple rooms or units, as it ensures consistency and reliability across the entire property.
