Abstract: Disclosed is a measurement probe for a measurement of elements in a mineral slurry. The measurement probe includes a housing having an X-ray window. The housing encloses: an X ray source positioned to emit source X-rays at the X-ray window; an X-ray detector positioned to detect X-rays from the X-ray window; and a control module. The control module is configured to: control an operation of the X-ray source and the X-ray detector; process X-rays detected by the X-ray detector to generate X-ray spectra data; and process the X-ray spectra data to determine a quantity of one or more elements of interest in the mineral slurry. The measurement probe further includes a probe mount adapted to couple the measurement probe to a pipe mount on a pipe carrying the mineral slurry; when the probe mount is coupled to the pipe mount, the X-ray window provides a transmission window for X-rays into a lumen of the pipe.

Abstract: The invention concerns radiographic equipment for forming an image of an interior of an object. The equipment comprises a source of X-ray or gamma-ray radiation having two or more energies and operable to irradiate an object to be scanned and a radiation source producing neutrons operable to irradiate the object. The equipment also comprises a radiation detector array having a plurality of pixels, each sensitive to and arranged with respect to the X-ray or gamma-ray radiation source and the neutron producing radiation source and operable to measure the intensity of each type of radiation transmitted through the object; means to process the intensity of each type of radiation, to determine the attenuation of each type of radiation having passed through the object, and to form an image indicative of the shape and composition of the object's interior.
