Radon Risk in Oregon

In Oregon, approximately 276 radon-related lung cancer deaths happen each year.

The Oregon Public Health Division recommends that ALL residences be tested for radon regardless of the risk level assigned to the home's geographic location.

The data presented in the links below was compiled by the Oregon Public Health Division. It contains long-term radon tests (more than 90 days) and short-term radon tests (2-90 days) that have been conducted primarily by homeowners. Indoor radon levels can be influenced by weather, season, geology, type of construction and heating, ventilation and air conditioning systems. Because of this, radon levels may not be consistent among a group of homes, even those next door to each other.

The maps and table provided here should not be used to substitute for radon testing of an individual home. The only way to know if you have high radon levels in your home is to test YOUR home.

The following Oregon counties have radon mitigation code requirements for new construction: Baker, Clackamas, Hood River, Multnomah, Polk, Washington, and Yamhill counties. The Appendix F: Radon Control Methods (pdf) details the mitigation requirements for each of these counties.
