Abstract: A scanning apparatus for measuring the attenuation of radiation passing from a radiation source along a radiation path to a radiation detector includes a source of radiation; at least one radiation detector capable of detecting radiation emitted by the source a data processor associated with the at least one radiation detector for calculating a property of material present in a linear radiation path between the source and the at least one detector; and a spacer arranged between the source and the at least one detector. The spacer defines a space which is capable of excluding water and having an average density which is less than 1 gcm−3. The provision of a spacer in the radiation path enables more radiation to be passed along the radiation path because water can be replaced with a material which is less attenuating to radiation.

Abstract: An apparatus and method for scanning a structure for detecting variations in density of a structure, the apparatus (10) includes: a source of radiation (20); a plurality of detectors (30), arranged for receiving radiation emitted by the source along a plurality of respective paths (26); the apparatus configured such that, a structure (100) to be scanned is positionable between the detectors and the source; collimation elements (40) including a plurality of collimator channels (42), each located between a respective detector and the source; and collimation adjustment element (60). The apparatus, in a first configuration, provides a first resolution (r1) in an axial direction substantially orthogonal to a plane including the source and plurality of paths; and, in a second configuration, the collimation adjustment element is positioned between the collimation elements and the source such that the apparatus provides a second resolution (r2) in the axial direction; wherein r2

Abstract: An apparatus for detecting radiation for obtaining density information of a structure, the apparatus including: at least one detector (10), the detector (10) including: a scintillator (12) including a scintillating material for emitting light in response to incident radiation (14), and a photodetector (16) for receiving light emitted by the scintillating material (12) and outputting an electrical signal in response to light received from the scintillating material (12), wherein the photodetector (16) includes at least one silicon photomultiplier (16a). The invention reduces the volume of the apparatus and therefore provides particular advantages for use in scanning pipelines and other structures located deep subsea.

Abstract: A source container for a radiation source includes a vessel having an external wall defining a space within which is located a shield formed from a radiation absorbing material and defining a cavity for receiving a radiation source, the shield including a window extending from the cavity through the radiation absorbing material, and at least two shutters, each shutter being movable between a closed position in which the shutter covers the window and an open position in which the shutter does not cover the window. The provision of two or more shutters provides a way to emit radiation of different intensities from the same source and container.
