Abstract
A prospecting system for hydrocarbons using emanoradiation measurements of the neutron, beta, gamma rays, and radon gas emitted at the earth surface and atmosphere from the earth basement complex and, the overlying sedimentary deposits of carbonaceous rocks, shales and sandstone that are impregnated with uranium, thorium and potassium derived from the eroded earth basement complex materials. A number of check points are measured and the radiation levels are plotted to form a georadiograph. A comparison between the background level and the check point levels is used in determining the contour data basically of the earth's stratosphere, altered in its variation by hydrocarbons, radiation active substances, and/or mineral deposits.
