Radiation detection apparatus and method

摘要

An apparatus for detecting radiation for obtaining density information of a structure, the apparatus comprising: at least one detector (10), the detector (10) comprising: a scintillator (12) comprising 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) comprises 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.
