    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: A detector probe, for detecting ionizing radiation and which is suitable for use in a nucleonic instrument usable in locations having a high ambient temperature, includes an array of radiation detectors mounted on a support and a heat pipe for cooling the detector probe. The nucleonic instrument incorporating such a detector probe is also described.

    Abstract: A subsea apparatus and method for scanning a subsea structure to detect differences in density between different parts of the subsea structure is described. A source of gamma radiation and a plurality of detectors arranged to detect gamma radiation emitted by the source are provided. The subsea structure is positioned between the source and the detectors, and the detectors and the source rotated in a fixed relationship to each other about an axis of rotation located between the detectors and the source. The plurality of detectors are arranged in a linear array, the linear array being substantially parallel to the axis of rotation. A pixelated detector array and a source container are also disclosed.

    Abstract: An apparatus for scanning a structure to detect density differences between different structure parts, the apparatus includes a source of gamma radiation, a plurality of first detectors arranged to detect radiation emitted by the source along a plurality of respective first paths, a plurality of second detectors arranged to detect radiation emitted by the source along a plurality of respective second paths. Each first and second path is substantially aligned with a respective radius of a circle centered on the source, and an angular separation between at least two neighboring first paths is S. The first and second detectors and the source are arranged for rotation in a fixed relationship with respect to each other, about an axis of rotation located between the source and detectors, wherein the axis of rotation is substantially orthogonal to the circle. An asymmetric collimator block directs gamma radiation from the source to the detectors.
