Department of Natural Resources Geological and Geophysical Surveys Portal allows users to share, discover, and access geologic data, maps, and applications. The portal hosts the Alaska Radon Web App. The app presents radon observation statistics. It allows the viewer to zoom to the location and obtain data, such as:
Radon Observation Statistics
for 1024 sq km hexagon
picocuries per liter (pCi/L)
Minimum: 0.90 pCi/L
Mean: 11.62 pCi/L
Median: 8.50 pCi/L
Maximum: 28.00 pCi/L
Number of Observations: 12
In order to continue building the Alaska Radon Database, the program asks users to share radon test results with the Alaska Division of Geological & Geophysical Surveys. A questionnaire is available for contributing data at (http://dggs.alaska.gov/hazards/download/radon-questionnaire.pdf). Test results and environmental data will be statistically merged with other radon data before it is made available to the public. Test results and personally identifying information such as addresses will be kept confidential except in the event a court of law orders that they be produced.
The radon-potential layer, which can be added to the map, is modeled from available test results and three statewide datasets, uranium in soils and sediments, depth to water table (and permafrost), and geology.

Note: This project began with funding from the EPA's Environmental Information Exchange Network and continues with funding from the EPA's State Indoor Radon Grant to Alaska's Department of Environmental Conservation, Division of Air Quality. The grant is implemented through a partnership of DGGS and UAF's Cooperative Extension Service.
