ABS>Mockups consisting of Fe containers filled with U ores were used for investigating the dependence of the energy spectrum on the specific weight of the ores. The differential spectra of the gamma -radiation showed a shift of the soft portion of the radiation toward the low-energy region as the weight of the ore in the mockups decreased. The shapes of the curves were quite similar. In the case of the integral spectra the absorption curves did not differ by more than plus or minus 6% for the different energy regions, indicating that the core sampling error is in the same order of magnitude. In order to compare logging data obtained with dif- . ferent casings, the correction factor for the absorption of gamma -radiation by the Fe wall must be known. On the basis of the tests it is found necessary to determine the exact location of the level of discrimination, otherwise the gamma anomalies cannot be interpreted quantitatively. (TTT)
