| Abstract: | A method for analyzing U and Th in radioactive ores by radioisotope excited X-ray fluorescence is described. For the proposed analysis, the theoretical and experimental factors that affect the sensitivity of the radioisotope XRF technique were investigated. Minimum detection limits of 13 ppm and 108 ppm can be achieved for U and Th, respectively, with a total counting time of 1000 s on a powdered ore sample. Results obtained in the analyses of radioactive ores from Turkey and BL-5 candidate reference uranium ores from CANMET (Canada Centre for Mineral and Energy Technology) are reported. |
