The following report covers the results of a general program that was conducted at the Oak Ridge National Laboratory to investigate the effects on plastic materials of exposure to radiation in the pile. In the investigation, several plastics were irradiated, and on removal from the pile, their rates of decay were determined by measurement of gamma activity in an ionization chamber.

Report discussing an investigation of radioactive Chattanooga black shale found in east central Tennessee.

The following report is based on the observations made during a visit to the Oak Ride National Laboratories of their Redox Pilot Plant equipment.

Report discussing an Chattanooga shale adit for laboratory test samples of rock and gaining information regarding mining conditions.

Report issued by the U.S. Bureau of Mines on the exploration of zinc ore deposits surrounding the Powell River area in Tennessee. Drilling methods and ore concentrates are presented. This report includes tables, and maps.

From abstract: Perry and Lewis Counties, east of the Tennessee River, in west-middle Tennessee, are underlain by nearly flat-lying rocks of Paleozoic age, with Mississippian cherty limestones forming the greater part of the surface of the western Highland Rim Plateau ridges. Near the summits of the ridges there is a fairly definite horizon in the chert that contains manganese and iron oxides in varying degrees of concentration. Weathering of the mineralized chert has produced widespread float on the hill slopes and in the beds of small spring branches, and the presence of this float, some of it rich enough for metallurgical manganese ore, has encouraged a search for promising deposits in place. In the present study 52 localities where the mineralized beds crop out or have been prospected were examined.

The following report describes the findings from an investigation of a uranium-bearing strata undertaken in Hickman and adjacent counties in west-central Tennessee during the summer and fall of 1944. The strata contained radioactive elements within the Chattanooga shale and the Maury glauconitic member of the Ridgetop shale.

Report discussing the U.S. Geological Survey's investigation of the radioactivity measurements of asphalltites, coals and shales found in Tennessee, Kentucky, West Virginia, and Pennsylvania.

Report issued by the Bureau of Mines over the operations of the Nonmetals Division during 1942. The work done by the division is discussed. This report includes tables, illustrations, and photographs.
