Radon is a colorless, odorless, and tasteless gas that forms naturally from the radioactive decay of uranium in rocks, surficial materials, and soils over millions of years. After formation, radon can move through fractures and layering in rocks or through connected pores in surficial materials and soils and enter a home through the foundation. Exposure to radon in indoor air is estimated by the Environmental Protection Agency (EPA) to be the second leading cause of lung cancer, with smoking being the first.

Open File reports include 1:24,000 scale bedrock, surficial, and groundwater maps published between 1963 and the present. Open File reports have a minimal level of review for conformance with editorial standards. All interpretations are those of the author. Most recent maps are Open File reports and include GIS data.
State Parks publications are illustrated booklets on the geology of some of the state parks and forests in Vermont. For the general interest reader.
