Radioactivity in the "Okpilak" Gneissic Granite Mount Michelson Area, Northeastern Alaska
The following report discusses radioactive results found in 4 samples of gneissic granite of 13 samples collected from the Mount Michelson area of northeastern Alaska. A mineralogic study of all heavy-mineral fractions having more than 0.01 percent equivalent uranium indicates that the radioactive material apparently is confined to biotite, which in one sample contains 1.19 percent uranium.
