In the period 1907 to 1944 inclusive only about 328 valid permits and licenses to appropriate ground water were issued by the state. thereafter 28 permits became...
Airborne radioactivity surveys for phosphate in Florida
Robert M. Moxham
1954, Circular 230
Airborne radioactivity surveys totaling 5, 600 traverse miles were made in 10 areas in Florida, which were thought to be geologically favorable for deposits of uraniferous phosphate. Abnormal radioactivity was recorded in 8 of the 10 areas surveyed. The anomalies are located in Bradford, Clay, Columbia, DeSoto, Dixie, Lake, Marion,...

The country rock in the vicinity of the mine is schist of pre-Cambrian age intruded by...
Radioactive deposits of Nevada
T.G. Lovering
1954, Bulletin 1009-C
Thirty-five occurrences of radioactive rocks had been reported from Nevada prior to 1952. Twenty-five of these had been investigated by personnel of the U. S. Geological Surveyor of the U. S. Atomic Energy Commission. Of those investigated, uranium minerals were identified at 13 sites; two sites contained a thorium mineral...
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...
