U.S. Geological Survey - The Geology of Radon

Sources of Radon Information

State Geological Surveys are good sources of information (geologic maps and radioactivity surveys) on the geology of the states. For information on soils in your area, the first place to start is the county agricultural extension agent. Telephone numbers and addresses for these state and county government agencies are in the phone book.

All states have radon contact agencies, usually the state health departments or divisions of environmental or radiation protection. These agencies and the regional offices of the U.S. Environmental Protection Agency (EPA) are good sources of general information about the health risks of radon, radon measurements in your house, and corrections of radon problems. The publications listed under "Suggested Readings - General References" are among those available from EPA. Many state radon agencies have these or similar publications available. For technical information on the geology of radon, look at the publications listed under "Suggested Readings - Technical References".
