The Washington State Department of Health provides outreach and information for the public to encourage testing and mitigation for radon. The Department states that radon is the single largest source of radiation for almost everyone in Washington and makes an effort to inform individuals about the radon potentials in their area.
The Washington Tracking Network provides information by topic (such as radon) or by location in its Community Reports tool. The Radon Mobile Data or "On The Go" map makes viewing environmental health data maps easy on mobile devices and reveals the environmental conditions in the locations where the user is present.
There are three map topics available: Radon, Lead Exposure Risk, and Smoke & Air. Various map feature overlays can be turned on and off to show locations such as clinics, schools and daycares. See https://doh.wa.gov/data-statistical-reports/washington-tracking-network-wtn/wtn-go
Mapping allows exploration of areas of the state color-coded for radon geology for high, medium and guarded areas. The map shows the potential to be exposed to radon based on characteristics of the surface geology:
• High, geology contains uranium, or has rock types known to contain uranium.
• Medium (variable), geology may have uranium containing rock deposited from glacial or other events.
• Low, geology or soil type unlikely to contain uranium.
The Division of Geology and Earth Resources at the Washington State Department of Natural Resources evaluated surface geology based on standards established by USGS. Approximately 57,000 uniquely identifiable rock and soil areas were classified into high, variable or low risk of producing radon gas.
The Department notes rocks or soil that contain uranium and its product, radon gas, can be anywhere in the state. Areas are classified with various risk areas but there is no area with no risk at all.
