Radon Potential Zone Map for the Lake Tahoe Area,California

MAP USAGE AND LIMITATIONS

This map identifies areas where geologic conditions are more likely to produceexcessive indoor radon levels. The map is intended to be advisory only. It isintended to assist national, state and local governments and organizations intargeting their radon program activities and resources. This map is not intendedfor determining which buildings have excessive indoor radon levels. Besidesgeology, local variability in such factors as soil permeability, weather and climaticconditions, building design and condition, and building usage also influenceindoor radon levels. Consequently, building-specific radon levels can only bedetermined by indoor radon testing. No warranty as to actual radon levels atspecific sites is expressed or implied by this map or the accompanying report.

The U.S. Environmental Protection Agency (EPA) recommends that all homes betested for radon whatever their geographic location. Homes with elevated radonlevels have been found in all zones within the Lake Tahoe area. The U.S. EPArecommends that action be taken to reduce radon in homes with an averageannual level higher than four picocuries per liter (4 pCi/l).
