ABSTRACT:
A cylindrical probe for insertion into a drill hole for detecting the presence of mineral deposits. A source of radioactive irradiation and a detector are mounted concentrically within the housing of the probe, the detector being shielded from direct radiation by a wall having an upper conical surface which directs fluorescent radiation reflected from the wall of the drill hole to the detector. A disc-shaped slot concentrates the rays from the radioactive source on an area of the drill hole wall which is in the shape of a ring surrounding the probe. The concentration and close proximity of the radiation source and the detector permit precise scanning and analyzing, simply, cheaply and quickly.
