Radiometric determination of uranium, thorium and potassium in some rocks of the Guanajuato Mineral district, México.
Main Article Content
Abstract
Uranium, Thorium and Potassium contents of some igneous and sedimentary rocks of the Guanajuato Mineral District have been measured by γ-ray scintillation spectrometry. Preliminary measurements show that the area studied is not a province of high radioactive contents. The data obtained for different rocks types is, in general, consistent with what has been found in other areas. The average K/U ratio is close to 1 x 10⁴ and K/Th ratio 3.9 x 10ᶟ in agreement with the figures established in the literature .
