Abstract
Approximate uranium concentrations in rock samples from the Sokoto Basin of Nigeria were predicted from γ-equivalent uranium and thorium (eU and eTh) measurements which made use of similar rock samples, previously analyzed by delayed neutron counting (DNC) and x-ray fluorescence (XRF) techniques, as reference materials. Comparison of the results of the 3 techniques shows that the eU values approximate the DNC results more than the XRF results do, with standard error of estimate of ± 6.68 ppm eU and correlation coefficient of 0.984. Corresponding values for XRF analyses are ± 32.53 ppm U and 0.730, respectively.
