Oregon Health Authority and Radon Resistant New Construction

by Margaret Henderson

The Oregon Health Authority Radon Awareness Program encourages radon resistant new construction (RRNC) in the state. Much of the State of Oregon is at risk for elevated radon levels as displayed in mapping indicating radon measurements throughout the state. https://geo.maps.arcgis.com/apps/Styler/index.html?appid=b48af2492fac4dd7857e5601c54dbf0f. Several counties in Oregon require RRNC, including Baker, Clackamas, Hood River, Multnomah, Polk, Washington and Yamhill. By Oregon statue, RRNC is required in all public buildings (including schools) and residences built after April 1, 2013, in these seven Oregon counties.

As part of its outreach to educate the public about radon health hazards, the Program encourages education and training with respect to RRNC. On its website, the Program answers the question, “What is Radon Resistant New Construction (RRNC)?” at https://www.oregon.gov/oha/PH/HEALTHYENVIRONMENTS/HEALTHYNEIGHBORHOODS/RADONGAS/Pages/Radon-FAQs.aspx#rrnc.

Training about RRNC is provided in the state by the Oregon Home Builders Association through its University. The Radon Awareness Program provides a link to this training on its website. See the University at https://homebuildersuniversity.com/oregon-builder-contractor-classes-online/#series-a-classes

RRNC training is provided in two separate courses:

· Package 1 – Oregon Construction Code includes a segment on Radon Mitigation – Appendix F.

· Radon and the Code is a course that provides review of the requirement for RRNC per the Oregon Residential Specialty Code Appendix F.
