Certified Radon Measurement Companies

The following is a list of radon measurement companies located in Oregon with at least one radon measurement technician on staff who has been certified by the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB). Current listings of certified measurement technicians, including those in neighboring states, can be found at their respective web sites, www.nrpp.info and www.nrsb.org.

This list should be used for informational purposes only and is not intended to be an endorsement by the Oregon Health Authority of any measurement company.
