    摘要: A device for measuring radioactivity for a machine for use in the extraction of radioactive ore and including at least one moving receptacle (18) suitable for containing a load of ore. The device comprises a rod (120) having its top end hinged to the machine in such a manner as to leave the rod free to swing in at least one vertical plane, the bottom end of the rod having a radioactive radiation detector (122) covering a determined solid angle, the device further including displacement means (140, 166) for bringing the rod and the receptacle in reproducible manner into a mutual disposition such that the load of ore contained in the receptacle occupies a substantial portion of the solid angle of the detector. An arm (110) is preferably provided between the rod and the machine.
