Report discussing the investigation of radioactivity in coal beds and associated rocks from the Pottsville, Allegheny, and Conemaugh formations in Beaver, Clearfield, and Jefferson counties, Pennsylvania. The report provides information regarding the procedures used, descriptive geology of the areas, radioactivity data, factors affecting the occurrence of radioactivity, and a summary.

Report discussing a study of samples taken from "commercially important coal beds and associated rocks in the Pottsville, Allegheny, and Monongahela series of the Pennsylvanian system". The report contains sections on the scope of the investigation, stratigraphy, radioactivity and uranium content of the coal beds and carbonaceous shale, and descriptions of the rock exposures examined.

The following report covers a reconnaissance for radioactive materials that was made in parts of Maine, New York, New Jersey, and Pennsylvania. It's primary objective was to examine the iron ore deposits and associated rocks in Adirondack Mountains of New York and the Highlands of New Jersey. Additionally, several deposits known or reported to contain radioactive minerals were examined to delimit their extent. However, most of the deposits examined are not significant as possible sources of radioactive elements and the data pertaining to them are summarized in tables provided.
