New statewide map of radon potential

thumbnail of map sheet from DOGAMI O-18-01, Radon potential in Oregon


Radon is produced in the natural decay of uranium, which is found in trace amounts in all rocks and soils. The map shows areas where Oregon’s underlying geology is more likely to produce radon. See radon potential information in Oregon HazVu.

Testing your home is the only way to know if radon is present. Learn more from the Oregon Health Authority about radon risk in Oregon and testing your home for radon.

Oregon historical mining information available online 

Historical mine and commodities records, formerly available to the public at DOGAMI Portland and Grants Pass office reference libraries, are now available as PDF files in the Oregon Historical Mining Information (OHMI) archive. The first part of this ongoing project includes small-dimension maps, letters, news clippings, photographs, and reports. The agency plans to combine OHMI records with the GIS-based Mineral Information Layer for Oregon (MILO).

MILO-2 is a geospatial database that stores and manages information regarding Oregon's mineral occurrences, prospects, and mines. A subset of the data is shown on the interactive map.
