Abstract

Coincidence and anti-coincidence counting rate meters and also an air conductivity meter have been installed in a transport plane to measure gamma radiation from ground sources. Materials containing 0.01 percent uranium can be detected at 500 feet and at an airspeed of 150 miles per hour.

Proposed program for and present status of the Geological Survey's investigation of domestic resources of radioactive raw materials

This interim report is designed to show the present status of the Geological Survey's information and the parts of a comprehensive program necessary to improve our information about the raw material resources of uranium and thorium. Rarely in geologic work has it been necessary. to determine so completely a nation's resources of useful minerals in so brief a span of time. Ordinarily, information on mineral resources Is accumulated during a long period of years. However, uranium and thorium were suddenly thrust from a position of subsidiary economic interest into one of great strategic importance. Information concerning their occurrence must, therefore, be obtained as rapidly as reliable methods of investigation will permit. Accordingly the program must be at once comprehensive and carried out over an area more extensive than is usual in the search for and appraisal of most other mineral resources.
