| Abstract: | The paper discusses the low energy gamma determination of ~(235)U, ~(238)U, ~(226)Ra and ~(232)Th contents in uranium ores and presents a simple and precise method for sample self-absorption calibration. The better analytical accuracy and precision for the determination of ~(235)U, ~(238)U, or ~(235)U/~(238)U in uranium samples are achieved. |
