Spectrometry (Radiometric Surveying)
The method allows investigating, in certain energy windows, the signal y associated with instable isotopes, relative concentrations of radioactive elements associated with minerals present in rocks, soils and in solution within the first tenth of meter in the underground. Potassium (dominant alteration indicator in most mineral deposits), Thorium and Uranium are the three most abundant radioactive elements on earth. By the time the concentration of these radio elements varies in different types of rocks and as a function of certain alteration/pollution processes, the use of the spectrometer may contribute in the geo scientist quest to define lithologic aspects, soil geochemistry, alteration zones,. etc.
