The Wyoming State Geological Survey has recently enhanced its interactive Wyoming Geologic Hazards Map by adding new layers that visualize the potential for radon occurrence across the state. Radon, a colorless and odorless radioactive gas, is the second leading cause of lung cancer in the United States after smoking. This gas originates from the natural decay of uranium in rock, soil, and groundwater.
The updated map layers are designed to help residents better understand the radon risks in different areas. These layers incorporate data from previous WSGS publications and health statistics from the Wyoming Department of Health, offering a valuable tool for identifying regions with potentially elevated radon levels.
Understanding Radon Risks: Radon exposure is a significant health risk, particularly in enclosed spaces where it can accumulate to dangerous levels. Despite its dangers, radon is often underappreciated as a geologic hazard. The new map layers aim to change this by providing easy access to localized radon potential data.
Localized Variations: It’s important to note that radon levels can vary significantly, even within the same area, due to local geological and non-geological factors. Consequently, areas not specifically highlighted on the map might still possess high radon potential, and vice versa. The WSGS emphasizes that the only way to accurately assess radon levels in a specific building is through direct testing.
Testing and Mitigation: The U.S. Environmental Protection Agency (EPA) recommends that buildings with radon concentrations at or above 4.0 picocuries per liter (pCi/L) should undergo mitigation measures, and those with levels between 2.0 and 4.0 pCi/L should consider mitigation. To aid in radon assessment, the Wyoming Department of Health offers free or discounted radon testing kits to state residents.
Additional Map Features: Besides radon, the Wyoming Geologic Hazards Map also provides information on other natural hazards like earthquakes, landslides, and expansive soils. This tool is regularly updated to reflect the most current data and insights available.
The addition of radon data to the Wyoming Geologic Hazards Map is a crucial step forward in public health and safety, providing residents with the resources needed to protect themselves from this invisible hazard.
