Investigation of the Spectra of Scattered gamma Radiation for the Inversion Region of gamma--Gamma Sondes

摘要

The gamma-gamma method (GGM) is used for sampling the ores of heavy elements (lead, mercury, tungsten, etc.). This method is characterized by rapidity, high performance and efficiency when compared with geological testing methods. Irregularities in the surface under investigation (porosity of the walls of holes, etc.) and variable density in the ores are the serious obstacles that impede successful use of GGM. Inversion sondes have been proposed to eliminate these drawbacks. The results of a study of spectral distribution of scattered gamma radiation in conjunction with two types of inversion sondes are discussed. (ERA citation 03:053392)
