Reconnaissance for Radioactivity in the Gold Hill Mining Area, Boulder County, Colorado, Part 1
Abstract: Several radioactive deposits were found as a result of reconnaissance in the Gold Hill mining area, Boulder County, Colo. The ore deposits of the area have been worked chiefly for gold. All ore shipped has come from fissure veins, most of which are gold telluride veins. There are, however, some important sulfide veins which show a vague zonal distribution of pyritic gold ores and silverlead ores. The results of this reconnaissance suggest a possible relationship of the radioactive deposits to this indistinct sulfide zoning; however, the zoning is so obscure that its practical application to prospecting for uranium is of doubtful value at the present time. Pitchblende, torbernite, metatorbernite, and schroeckingerite have been identified in specimens from the area; however, no uranium minerals have yet been identified from most of the radioactive deposits, and the uraniferous material present is probably in disseminated small particles. Although selected samples from several localities assay 0.10 percent uranium or more, the known deposits are small and probably are not of immediate economic importance

Wagon-Drill Sampling by U.S. Geological Survey
Abstract: For a number of years the Geological Survey has employed core drilling as a means of obtaining samples of underground formations for use in exploring and evaluating mineral deposits. During 1951, however, experiment with less expensive methods showed that, for analytical purposes, wagon-drill cuttings could be used as effectively as cores, provided a practical method were devised for recovering them in suitable form. The recent development of such a method has made it possible, in places where the depth of drilling does not exceed 125 feet, to supplant thousands of feet of core drilling by wagon drilling which is much faster and which can be done at approximately one-third the cost of the former method. This report describes the sampler and discusses performance, maintenance, and operating costs.

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.

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.
