The Oregon Indoor Radon Risk map, 2024 edition, is available online at the Oregon Health Authority radon website.
The map presents risks calculated using a classification system based on three factors:
• Maximum observed radon test result value
• Average radon test result value
• Percent of location with a radon test result that was greater than or equal to 4 pCi/L within the zip code.
Points are assigned based on these factors and risk level is presented as Low, Moderate, and High. This map summarizes indoor radon test results voluntarily given to the Oregon Radon Program by radon test kit manufacturers.
Free radon tests are provided by the Authority for use in testing residences in qualifying zip code area listed on the website.
