Measurement Companies

The following is a list of radon measurement companies servicing 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 can be found at their respective web sites, www.nrpp.info and www.nrsb.org.
