Radon Assessment

Steer Environmental conducts radon characterization in residential, commercial, industrial, and institutional buildings, and perform preliminary assessment and design of mitigation systems in accordance with As Low As Reasonably Achievable (ALARA) principles to achieve indoor environments that are safe for occupancy. 

We employ C-NRPP-trained and CARST-certified radon measurement professionals offering the following testing options:

• Short-term Testing (2-7 days, long-term test still recommended)
• Long-term Testing (>90 days, winter months recommended)
• Post-mitigation Follow-up Testing

Continuous Radon Monitors (CRMs) are used to perform short-term tests to determine whether long-term testing is recommended and/or mitigation requirements. CRMs are advantageous relative to Alpha track detector or Electret ion detector test units, as CRMs allow for data download and review to determine potential environmental patterns of influence. Alpha track and Electret ion devices are limited to providing a temporal average. 

We work closely with radon mitigation professionals to recommend and execute installation of the following mitigation systems as and when required:

• Interior Active Soil Depressurization
• Exterior Active Soil Depressurization
• Sub-Slab Active Soil Depressurization  
• Crawlspace Sub-Membrane Depressurization
• Sump-Hole Depressurization
