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 the Environmental Protection Agency (EPA) shows has 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 houses can have unhealthy radon levels.
USGS research on radon has mostly been limited to its presence in groundwater. The Environmental Protection Agency (EPA) is the best starting point for information about air quality and radon in buildings.

What is radon?
Radon is a naturally occurring gas produced by the radioactive decay of the element radium. Radon itself is radioactive and it decays to form the element polonium. Polonium is also radioactive and it is this element, which is produced by radon in the air and in people's lungs, that can hurt lung tissue and cause lung cancer. Radon is ubiquitous (usually in small amounts) in rock and soil and can...

Evaluation of radon occurrence in groundwater from 16 geologic units in Pennsylvania, 1986–2015, with application to potential radon exposure from groundwater and indoor air
Results from 1,041 groundwater samples collected during 1986‒2015 from 16 geologic units in Pennsylvania, associated with 25 or more groundwater samples with concentrations of radon-222, were evaluated in an effort to identify variations in radon-222 activities or concentrations and to classify potential radon-222 exposure from groundwater and indoor air. Radon-222 is hereafter referred to as “radAuthorsEliza L. GrossThe quality of our nation’s waters: Quality of water from domestic wells in principal aquifers of the United States, 1991–2004— Overview of major findings
More than 43 million people - about 15 percent of the U.S. population - rely on domestic wells as their source of drinking water (Hutson and others, 2004). The quality and safety of water from domestic wells, also known as private wells, are not regulated by the Federal Safe Drinking Water Act or, in most cases, by state laws. Rather, individual homeowners are responsible for maintaining their domAuthorsLeslie A. DeSimone, Pixie A. Hamilton, Robert J. GilliomUranium and radon in ground water in the lower Illinois River basin
Uranium and radon are present in ground water throughout the United States, along with other naturally occurring radionuclides. The occurrence and distribution of uranium and radon are of concern because these radionuclides are carcinogens that can be ingested through drinking water. As part of the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) program, water samples wereAuthorsWilliam S. MorrowNaturally occurring radionuclides in the ground water of southeastern Pennsylvania
Naturally occurring radionuclides in the ground water of southeastern Pennsylvania may pose a health hazard to some residents, especially those drinking water from wells drilled in the Chickies Quartzite. Water from 46 percent of wells sampled in the Chickies Quartzite and 7 percent of wells sampled in other geologic formations exceeded the U.S. Environmental Protection Agency (USEPA) maximum contAuthorsRonald A.

IntroductionA study of the occurrence and distribution of dissolved radon in the ground water of Chester County was undertaken by the U.S. Geological Survey (USGS) in cooperation with the Chester County Water Resources Authority and the Chester County Health Depart-ment. The results of this study are published in a technical report by Senior (1998). This fact sheet summarizes the key findings pre-sAuthorsRonald A. Sloto, Lisa A.

Ground-water samples collected from 267 wells were analyzed for radon as part of a water-quality reconnaissance of subunits of the Lower Susquehanna and Potomac River Basins conducted by the United States Geological Survey (USGS) as part of the National Water-Quality Assessment (NAWQA) program.
