A container design is described for the determination of elemental uranium in uranium-bearing ore by gamma-ray spectrometry. For the design the following criteria for the given detector collimator configuration are taken into account: (i) the degree of infinite thickness for the gamma-ray energy concerned should be about 95 %; (ii) the degree of infinite thickness should be maintained over the whole solid angle; (iii) the amount of ore should be as low as possible; (iv) the radiation window material and thickness should be well defined. Verification measurements show that the measured degree of infinite thickness of 94.4 % differs only by 0.6 % from the predicted degree of infinite thickness.
