Abstract

An examination is made of the results of a theoretical calculation of the hard γ-ray spectrum of uranium and thorium uniformly distributed in rock and in equilibrium with their decay products. The energy distribution of the pulses produced by this γ-emission in a scintillation γ-spectrometer is calculated. The results are presented in the form of graphs which enable one to carry out a calculation of the spectral effects expected in a spectrometric investigation of natural γ-emission. The necessity for such calculations arises in the development of γ-spectrometric methods of exploration and prospecting for useful minerals, such methods having lately come into wide use in geophysics.

Calculated coefficients of the equations for the separate determination of the uranium and thorium content in rock are also presented. Calculated spectrographs are presented, with a discussion concerning questions of the accuracy of spectrometric investigations when employed under the conditions of field geophysical observations.
