Radon-hazard Potential of Beaver Basin Area, Beaver County, Utah

Front Cover
Utah Geological Survey, Jan 20, 1998 - Geology, Structural - 38 pages

Indoor-radon levels in the Beaver basin of southwestern Utah are the highest recorded to date in Utah. Measured indoor-radon concentrations range from 17.5 to 495pCi/L. These levels are well above those considered a health risk by the U.S. Environmental Protection Agency. Both geologic (uranium content of soil, depth to ground water, soil permeability) and non-geologic (weather, home construction, life-style) factors affect indoor-radon levels. In this study, geologic factors are quantified and used to produce a radon-hazard-potential map of the Beaver basin area. The map helps prioritize radon testing and evaluation and the need for radon-resistant construction.
