Abstract

Radioactivity of nine samples of beach placer deposits in the Yakataga area, southern Alaska, was studied in 1948. The samples were given to the Geological Survey by prospectors operating in the area operating in the area. The heavy-mineral fractions from the concentrates average 0.044 percent equivalent uranium. Three minerals, all members of the zircon group, contain the radioactive material in the sample; one mineral is uranium-bearing, the other two are thorium-bearing. Unless the concentration of radioactive minerals in the beach deposits is considerably higher than the present qualitative data indicate, the placers at Yakataga beach do not constitute a feasible source of supply of radioactive materials.
