Measurement Companies 

The following is a list of radon measurement companies that provide service in Oregon and have been certified by the National Environmental Health Association (NEHA) or the National Radon Safety Board (NRSB). Current listings of certified companies can be found at their respective web sites, www.neha-nrpp.org 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 orgnaizations, NEHA and NRSB.

For more information about radon, contact the Radon Program.
