The Model VI transmission fluorimeter for the determination of uranium
Charles Alvin Kinser
1954, Circular 330
An improved transmission fluorimeter (Model VI) for use in the determination of uranium consists of a line-operated, low-voltage d-c supply, powering a small 3-watt ultraviolet lamp as a source of long wavelength ultraviolet radiation; a Model V phototube housing and. fluorimeter head containing the sample holder, shutter, and primary and...
Reconnaissance for radioactive deposits in east-central Alaska, 1949
Helmuth Wedow, M.G. White
1954, Circular 335
In the summer of 1949, several mines and prospects in the Fairbanks and Livengood quadrangles, east-central Alaska, were examined for the possible presence of radioactive materials. Also tested were metamorphic and sedimentary rocks of pre-Cambrian and Paleozoic age crossed by the Elliott Highway, which extends from Fox, near Fairbanks, northwestward...

Clyde Wahrhaftig, Joseph H. Birman
1954, Circular 310
Stripping-coal reserves in an area of about 9.4 square miles extending from the Nenana River about 6 miles up the valley of Lignite Creek are estimated to amount to about 95, 000, 000 tons. The stripping-coal reserves are located in the lower and middle members of the Tertiary coal-bearing formation....

Beryllium resources of the tin-spodumene belt, North Carolina
Wallace R. Griffitts
1954, Circular 309
Pegmatite dikes in the tin-spodumene belt of North and South Carolina uniformly contain about 0.05 percent BeO. The most abundant minerals in the pegmatite contain from 0. 0001 to 0.01 percent BeO. Beryl, having 12.0 to 12.3 percent BeO, is the only beryllium-rich mineral and contains more than 80 percent...
