Understanding Radon Risks in Commercial Buildings

Radon is a colorless, odorless gas that forms naturally when uranium in soil and rock breaks down. Prolonged exposure to high radon levels increases the risk of lung cancer, making radon mitigation essential for public health. Commercial buildings, especially those with large basements or lower levels, are particularly vulnerable to radon accumulation. In Portland and surrounding areas, radon concentrations can vary greatly due to geological factors.

Since radon seeps in through cracks in foundations or building materials, continuous testing is vital for ensuring safe indoor air quality. The Environmental Protection Agency (EPA) suggests action when radon levels reach 4.0 pCi/L, but the World Health Organization (WHO) recommends mitigation at 2.7 pCi/L. Therefore, understanding and controlling radon levels in commercial spaces such as schools, offices, and multifamily housing is critical to ensuring tenant safety and building compliance.

Environmental Works offers customized radon testing and mitigation solutions designed to meet the specific needs of commercial structures. Our team follows strict testing protocols and provides advanced mitigation systems to keep radon levels well below safety thresholds. By partnering with us, building owners and managers can maintain compliance with local regulations and protect their occupants from this silent but serious health hazard.

New Construction Passive Radon Systems 

As of April 2011 the State of Oregon adopted senate bill 1025 establishing minimum requirements for radon resistant new construction.  The state of Washington adopted similar radon system requirements years prior.

New residential and multi family structures must now have a minimum passive radon mitigation system according to EPA radon mitigation standards. These design standards are found in Appendix F of the Oregon Residential Specialty Code. 

The standards were adopted and implemented due to the risks associated with radon gas exposure in buildings and the simplicity and effectiveness of these systems when designed into the rough structure of the building. New construction systems often outperform retrofit systems for a lower installed cost, when installed correctly.
