Reliable Radon Testing & Mitigation for Dayton Businesses

Ensuring Workplace Safety with Professional Radon Testing

At Airduct Cleaning & Radon Co., we understand the importance of a safe work environment. The EPA recommends radon testing in workplaces due to employees' significant time indoors. Extended exposure to elevated radon levels poses serious health risks similar to those in homes.

Why Test for Radon?

  • Health Risks: Prolonged radon exposure increases the risk of lung cancer.
  • Regulatory Compliance: Guidelines for commercial properties are evolving to ensure worker safety.

Our commitment to regular radon testing and mitigation can help create a healthier work environment, avoid potential legal issues, and demonstrate our commitment to employee well-being. Just like homeowners, business owners must prioritize radon safety.

Commercial Radon Testing for Multifamily Properties

HUD currently requires that at least 25% of randomly selected ground-level units in existing properties be tested for radon, with mitigation required if high levels are found. This policy applies on a per-building basis, not per unit (source).

However, HUD rules may change. The AARST-ANSI standards protocol requires testing 100% of units, and enforcement is similar to mold testing (source).

Staying ahead of these changes ensures compliance and safeguards your tenants' health.

Considering Passive Mitigation Systems in Commercial Properties

Commercial and residential radon mitigation systems are similar. Both use a slab or sump pump as the entry point for piping to channel radon gas from the soil and diffuse it into the atmosphere.

However, commercial properties, including offices, apartments, retail stores, and condos, often have higher indoor airflow, which increases the "stack effect" and makes passive mitigation challenging. Engineering active systems for these locations can be complex.

Commercial buildings also have multiple structural types, leading to various radon entry points. Mitigation designs are often unique due to different variables and issues, making each project a custom solution.

Additionally, commercial mitigation installations must consider daily operations. Owners of retail, apartment, and office properties prefer minimal disruption to tenants, while schools, retail, and condo properties have their own specific concerns.

Active Mitigation Systems in Commercial Properties

Unlike residential active mitigation, which involves fans, commercial properties often use Active Soil Depressurization (ASD). ASD works by stabilizing and equalizing the pressure between the soil outside the building and the air inside.

Without ASD, the pressure in the surrounding soil is higher than inside the building, causing radon to be drawn in through tiny cracks and holes. This leads to indoor contamination. With ASD, soil depressurization equalizes the pressure inside and outside, drawing radon out from beneath the building and significantly reducing or eliminating indoor radon levels.


Ohio is a Radon “Hotspot”

Radon zones have been determined, and Ohio is one of the most seriously affected states. Central Ohio, including the Dayton area, is in the “high danger” zone. Many structures tested within that area will undoubtedly require mitigation.

Health Concerns- Radon is the Second Leading Cause of Lung Cancer

Radon is a radioactive heavy gas that enters homes through basements or slabs and includes very serious potential health hazards. Being in a building with a significant radon leaves people risk of lung cancer. Radon is the second leading cause of lung cancer in the United States. (Smoking is number one, and second-hand smoke is number 3.)

Testing and Mitigation Requirements

Once the danger of Radon was recognized, it still took time for the real estate market to actually accept the danger. Many mortgage lenders for residential properties are requiring testing – and mitigation – because of the liability they could face by not requiring the testing.
