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.

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. These organizations are not the only sources of radon testing services. There may be additional companies listed in your local phone book under "Radon Testing." There are additional organizations outside Oregon that can provide radon testing devices or services.

Homeowners can also purchase radon test kits at local hardware stores or through the Internet and test their homes themselves. Before purchasing, one should verify that the device or service meets the current requirements of the national certifying organizations, NRPP and NRSB.

For more information about radon, contact the Radon Program.
