Radon Contractor Licensing in Oklahoma

Oklahoma licensing

Oklahoma does not license or certify radon mitigation contractors at the state level. The Oklahoma Department of Environmental Quality runs the state radon program through its Land Protection Division, Radiation Management section, and directs residents to the national certifying bodies. Confirm a contractor holds National Radon Proficiency Program (NRPP) or National Radon Safety Board (NRSB) certification.
