Control Chart Method Applied to Errors in Radioactive Counting
Abstract: The Control Chart statistical methods, developed by Showhart for the control of quality of manufactured products, are applied to the control of Geiger-Miller counting instruments. Experiments are reported to show the use to the Control Chart method for detecting disturbances in instrumental behavior and for detecting radioactive effects so weak that they are near the limit of detection of the instruments. As a corollary, the control chart can be used to reduce to its practical limit the time required for tests.

Radioactivity and Mineralogy of Concentrates From the Placers of Julian, Moore, and Candle Creeks and the Cripple Creek Mountains, Lower Yukon-Kuskokwim Highlands Region, Alaska
Abstract: Radiometric and mineralogic study of 10 concentrate samples from the placers of Julian, Moore, and Candle Creeks, and the Cripple Creek Mountains, Lower Yukon-Kuskokwim Highlands region, Alaska, failed to reveal any significant amounts of uranium. Only the sample from Julian Creek shows and appreciable amount of radioactivity (0.03 percent equivalent uranium), but this is attributed entirely to thorium in monazite.

Reconnaissance for Trace Elements in North Dakota and Eastern Montana
From abstract: A reconnaissance for sources of radioactive material in North Dakota and eastern Montana was made in 1948. This reconnaissance was followed by a more detailed survey of parts of Golden Valley and Slope counties, southwestern North Dakota, in June 1949. The radioactivity of representative sections of all formations known to be exposed in the area and of three manganiferous spring deposits was determined with portable Geiger-Mueller counters. At 86 localities 82 samples were taken of these formations and also of 10 ground and surface waters.

Preliminary Report on Diamond-Drill Exploration of Parts of Blue and Moon Mesas, Mesa County, Colorado
From abstract and summary: The Blue and Moon Mesa areas are about 13 miles southeast of Gateway, Mesa County, Colo. Total production of carnotite ore from the Blue and Moon Mesa areas has been about 1,000 short tons that averaged about 0.25 percent U30Oand 1.75 percent V205. Most of this production was obtained from 1940 to 1943 and in 1949. The U. S. Geological Survey explored the northern parts of these areas by diamond drilling between August 9 and December 14, 1950. The Survey drilled 113 holes, totalling 16,039 feet. This drilling was mostly wide-spaced and was done to obtain geologic information.

Radiometric Examination of Rock Specimens from Mount McKinley, Alaska
Abstract: A suite of 50 rock specimens, collected by the 1947 Washburn Mount McKinley Expedition, was scanned radiometrically. The maximum radioactivity observed in any one of the specimens was about twice background. Radiometric analyses of the most radioactive samples show that a sample of vein quartz coated with manganese oxide contains 0.009 percent equivalent uranium and that the maximum equivalent uranium content of granitic rock types is .004 percent. The radioactivity of the manganese-stained quartz is probably due to traces of uranium in the manganese mineral, whereas that of the granitic rocks is due to radioactive accessory minerals.

A Semiquantitative Spectrographic Method for the Analysis of Minerals, Rocks, and Ores
From Abstract: "The semiquantitative method described determines 55 elements in one arcing of a 10-mg sample, requires a minimum of sample handling thus reducing the chances of contamination, detects low concentrations of elements, and is rapid."

Uranium and Phosphate in the Western Part of the Bonny Lake Mine, Polk County, Florida
From abstract: During the month of May 1950, the Davison Chemical Corporation, under contract with the Atomic Energy Commission, drilled 24 phosphate prospecting holes in the western part of the Bonny Lake mine, in the SW NW4 and the NW*SW4 sec. 32, T. 29 S., R. 24 E., Polk County, Fla. The purpose of this drilling was to obtain a comparison between tonnage and grade of uranium in the phosphate as indicated by prospecting, and the tonnage and grade of uranium in the phosphate products recovered in the mill. The results presented in this paper are based upon a study of drill cores, drill logs, gamma-ray logs, and the chemical analyses of drill-core samples.

A Semiquantitative Spectrographic Method for the Analysis of Minerals, Rocks, and Ores ([Part] 2)
Abstract: The scope of the semiquantitative spectrographic method for the analysis of minerals, rocks, and ores previously described as determining 55 elements, has now been increased to 68 elements which can be estimated in one exposure of a l0-mg sample. Fluorine, the 69th element, requires a separate exposure for some materials. The method has been used to complete about 185,000 determinations in the past two years. Listed in this report are 336 chemical check analyses that indicate approximately 8 percent disagreements in the magnitude of one 10 percent bracket. No chemical and spectrographic results differ by a factor of more than 10.
