Results from 1, groundwater samples collected during ‒ from 16 geologic units in Pennsylvania, associated with 25 or more groundwater samples with concentrations of radon, were evaluated in an effort to identify variations in radon activities or concentrations and to classify potential radon exposure from groundwater and. million to million homes (Exhibit 1). Exhibit 2 shows radon potential in homes at the county level based on indoor radon measurements, geology, aerial radioactivity, soil permeability, and foundation type. Zone 1 is the highest radon potential area, followed by Zone 2 (medium), and Zone 3 (low).
Geologic radon potential of EPA Region 10; Alaska, Idaho, Oregon, and Washington Open-File Report J Edited by: R.R. Schumann. You can get an idea as to how concerned you should be about radon in your house by learning about the geology of the site and its radon potential. If your house is in an area with a high potential for radon, then chances are that your house may have an indoor radon problem. However, the way a house is built can increase the risk - so even in areas of low radon potential, some.
Sources of Radon Information State Geological Surveys are good sources of information (geologic maps and radioactivity surveys) on the geology of the states.

Geologic radon potential of EPA Region 4 [microform]: Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee / U.S. Department of the Interior, U.S. Geological Survey ; prepared in cooperation with the U.S. Environmental Protection Agency The Survey: [Books and Open-File Reports Section, distributor] [Denver, Colo.] The USGS geologic radon potential books are organized by EPA region, with individual chapters for each of the 50 states.
The reports also include summaries of existing indoor radon data for each state. Return to USGS Radon Information. Geologic radon potential of EPA Region 4: Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee.
As part of an Interagency Agreement between the EPA and the U.S. Geological Survey (USGS), the USGS has prepared radon potential estimates for the United States. This report is one of ten booklets.
Three levels of radon potential were identified in the counties. Low radon potential means that the majority of homes contain less than 4 pCi/L of indoor radon. Moderate radon potential indicates that one-third to one-half of the homes have more than 4 pCi/L. High Radon potential means that the majority of homes contain more than 4 pCi/L.
Two of these four formation categories had median radon values of pCi/L or greater, the EPA action level for radon (U.S.
Environmental Protection Agency (EPA), ). The two geologic formation types with the highest radon levels were older bedrock units (Ordovician or Cited by: 7.

Results indicate that approximately 33% of the U.S. population lives within geologic provinces where the average indoor radon levels have the potential to be greater than 4 pCi/L ( Bq/m3).
The Indoor Radon Abatement Act of (Public Law ) directed the U.S. Environmental Protection Agency (EPA) to identify areas of the United States that have the potential to produce harmful levels of indoor radon.
These characterizations were. The geologic radon potential of the United States was recently assessed by the U.S. Geological Survey. Results indicate that approximately 33% of the U.S. population lives within geologic provinces where the average indoor radon levels have the potential to be greater than 4 pCi/L ( Bq/m 3).Rock types most commonly associated with high indoor radon include: 1) Uraniferous metamorphosed Cited by: Previous work by others and our own preliminary evaluations indicate that soil-gas radon levels are high enough to cause indoor air in homes to exceed 4 pCi/L, the U.S.
Environmental Protection Agency’s (EPA) action level for radon. A three-year study of the Geologic Radon Potential of the United States was recently released by the U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency (EPA). These geologic radon potential assessments were made using 5 types of data: 1.
building architecture; 2. aerial radiometric surveys; 3. soil. Of the 14 geologic formation categories in north central Kentucky, four were associated with median radon levels, ranging from to pCi/L.
Conclusion. Radon potential maps that account for geologic factors and observed radon values may be superior to using observed radon values Cited by: 7. In comparison with other geologic terranes, the Coastal Plain of the eastern and southern United States is a region of low to moderate radon potential with local areas of high radon potential.
Analyses were made of soil radon concentrations, soil permeability, and equivalent uranium concentrations. Data for Florida are from the Florida Statewide Radon Study.
County screening indoor radon averages range from less than 1 pCi/L to pCi/L. The geologic radon potential areas in Region 4 have been summarized from the individual state chapters and are shown in figure 3. Everglades R-EMAP is a program of the United States Environmental Protection Agency’s Region 4 Laboratory [the Science and Ecosystem Support Division (SESD) in Athens, Georgia], with the Region 4 Water Management Division (WMD) cooperating.
Everglades R-EMAP is managed by Peter Kalla of SESD. Daniel Scheidt of WMD is the associate manager. The maximum value recorded in the survey was pCi/L in Benton County. The average indoor radon for the state was pCi/L and percent of the homes tested had screening indoor radon levels exceeding 4 pCi/L.
