This is a geological report on the uranium mine in Hack's Canyon, Mohave County, Arizona.

Report explaining some different categories of special refractory materials. These categories of materials and their properties are discussed as well as the specific materials that fall into these categories.

Report describing the results of corrosion tests on 68 types of materials. Generally, most materials were tested with an agitator and vapor and some were tested a 3rd way with alternate immersion.

"The experience at Oak Ridge National Laboratory in decontamination equipment and working areas from radioactivity has been summarized." The methods and reagents that were used for decontamination are discussed.

A report made of the examination of a prospect in the White Signal mining district of Grant County, New Mexico.

Monthly report of the U.S. Geological Survey's trace element investigations including an outline of field work, laboratory work, and staff activities that have been completed or are in process.

Abstract: Part I: A series of extraction experiments has been performed to determine the distribution coefficient of uranium(VI) between dilute perchloric acid and benzene solutions of TTA. The data are interpreted to show that the principal species in the acid phase is a doubly charged ion, UO2++. The discrepancies revealed in previous work(1) were not found. Part II: The spectrophotometric method of analysis developed for use in Part I has shown the existence of previously unreported species of uranium(VI) in the presence of TTA: UO2K2-HK in benzene, and UO2K+ in dilute acid. The absorption spectra of all the principal species are reported.

A quarterly report consisting of reports published on Transuranic Elements from the University of California Radiation Laboratory. Each report is a brief one to two page summaries of the article submitted for publication during the months of September-November, 1948.
