The quantitative evaluation of uranium content in the Khoshomi boreholes has been mainly carried out based on logging and XRF laboratory data. In order to determine the correlation between aforesaid data, composition and chemical analysis has been accomplished at 115 zones by considering 3.05 meter intervals that is equal to the length of each drilling rod. In this relation, 55 parts with the core recovery coefficient more than 90% were selected and the correlation between their uranium and thorium contents were studied to determine the amount of radiation resulted from thorium. In the next stage, the regression equation was obtained using two methods, i.e. correlation between the total count and the uranium content, and the thorium depleted radiation and the uranium content. Using the first method, the average estimation error is approximately zero. But, as the estimated error variance is relatively high, complementary information is required for a favorable mining design.
