Radon Testing & Compliance

Radon is a naturally occurring, colorless, and odorless radioactive gas. It enters buildings through cracks and openings in foundations, floor slabs, and crawlspaces, and poses a significant health risk for occupants. Long-term exposure to elevated radon levels is the second leading cause of lung cancer in the United States.

Radon levels vary based on building design, soil conditions, and ventilation.

Testing is the only reliable way to determine whether a building has elevated radon concentrations.

Radon risk reduction, at scale

Shive-Hattery specializes in radon testing for large and complex buildings and campuses, including:

Multifamily housing complexes
Schools and school districts
Daycares and early childhood facilities
Commercial and office buildings
Senior living and assisted care communities

How we work

Custom test plans, minimal disruption. Our certified professionals design building-specific testing programs that account for size, layout, occupancy patterns, and use.

Short-term radon measurement devices are placed in representative, occupied spaces to characterize indoor radon concentrations and document conditions accurately. Multiple rooms and buildings can be evaluated simultaneously while minimizing disruption to occupants.

We test in accordance with nationally recognized protocols for large buildings and supports applicable state requirements and regulatory compliance.

In-house analysis for fastest results. Radon measurements are performed using Electret Ion Chambers (EIC) manufactured by Rad Elec, providing accurate and reliable evaluation of indoor radon levels. Shive-Hattery operates the only licensed EIC radon laboratory in the State of Iowa, enabling faster data processing, quality control, and streamlined reporting.

Mitigation support. We work closely with building owners and facility managers to interpret results, document compliance, and identify next steps when elevated radon levels are identified.

When mitigation is required, our team can assist with planning, coordination, and integration with existing building systems to help reduce radon concentrations—supporting informed decisions that protect occupant health and long-term building performance.
