How Commercial Radon Testing Works
Four steps from site assessment to written compliance report.
Site Assessment
We review your Mitchell building's footprint, occupied zones, HVAC configuration, and foundation type to design a multi-point testing protocol appropriate for the property's size and layout.
Multi-Point Placement
Testing devices are placed at multiple locations across the lowest occupied level — covering different zones of the building footprint to document spatial variation in radon levels throughout the space.
Test Period
Devices remain in place for the required test duration under closed-building conditions. We coordinate the process to minimize disruption to Mitchell business operations and daily schedules.
Compliance Report
Lab-certified results are compiled into a written compliance report documenting radon levels at each test point, compared to the EPA 4.0 pCi/L action level, with recommended next steps.
Mitchell Commercial Testing Context
Why Mitchell Commercial Buildings Need Radon Testing
Mitchell sits in Davison County — Zone 1 on the EPA's radon map, meaning average predicted radon is above 4.0 pCi/L. The James River valley glacial till soils and the broader geology of south-central South Dakota create conditions that produce elevated radon levels in basements and ground-floor spaces throughout the area. That risk applies to commercial buildings just as it does to residences.
Downtown Mitchell's commercial corridor, medical offices serving the region, school buildings, daycares, and businesses near the Corn Palace tourist district all occupy ground-level or below-grade spaces where workers and occupants spend extended hours. A single test device doesn't adequately represent a commercial building's full footprint — different sections of the same building can produce meaningfully different radon readings depending on sub-slab conditions, foundation features, and HVAC airflow patterns.
Multi-point placement across the lowest occupied level documents actual spatial variation rather than a single-point sample. The written compliance report we deliver is suitable for building owners, employers, commercial property managers, or parties to a commercial real estate transaction. If any test location exceeds 4.0 pCi/L, commercial mitigation is available and effective.

Commercial Radon Testing in Mitchell — FAQ
Yes. Mitchell and Davison County are Zone 1 — the EPA's highest radon risk category. The 4.0 pCi/L action level applies to any occupied building: offices, medical facilities, schools, daycares, retail, and any commercial space where workers or occupants spend significant time at or near ground level.
Downtown offices and retail buildings, medical offices and regional health clinics, school buildings, daycares, businesses along the main commercial corridors, and any building with below-grade occupied space. The James River valley glacial till that underlies Mitchell is Zone 1 territory throughout.
Commercial buildings have larger footprints than residences, and radon levels can vary significantly between different zones within the same building based on foundation features, sub-slab conditions, and HVAC airflow. Multi-point placement on the lowest occupied level documents actual spatial variation — not just one corner that may or may not represent the rest of the space.
The written report documents radon levels at each test location in your Mitchell building, compares them to the EPA's 4.0 pCi/L action level, and provides clear guidance on next steps if any location requires action. Suitable for building owners, property managers, employers, or parties to a commercial real estate transaction.
