The ore subjected to radioactive sorting treatment is crushed ore, with random shapes, which directly affects the accuracy of ore grade detection. To enhance the accuracy of radioactive separation detection, standard samples of uranium ore were prepared to conduct an influence test on how the shape of uranium ore affects detection efficiency. The relationship between the ore shape factor and the variation coefficient of detection efficiency was examined, leading to the establishment of a detection efficiency correction algorithm based on ore shape. Additionally, a quantification method for ore shape suitable for uranium ore radioactivity detection was proposed. The validity of the proposed detection efficiency correction algorithm has been verified through practical ore sorting tests. After implementing this algorithm, the error in uranium ore grade detection was reduced to less than 5% in over 70% of the test groups. This significantly mitigates the impact of ore shape on detection efficiency and enhances the accuracy of uranium ore grade detection.
