摘要： A gamma ray detector is described. The detector comprises a plastic scintillation body for receiving gamma rays and generating photons in response thereto. The scintillation body is in the form of a truncated cone defined by a base surface and an end surface separated along an axis of extent of the scintillation body with a lateral surface extending therebetween. A photodetector is optically coupled to the base surface of the scintillation body so as to detect photons generated by gamma ray interaction events within the scintillation body. A specular reflector is provided adjacent, but separated from, the lateral surface of the scintillation body so as to reflect photons that leave the scintillation body through the lateral surface back into the scintillation body.

摘要： The present invention provides a gamma-neutron detector based on mixtures of thermal neutron absorbers that produce heavy-particle emission following thermal capture. The detector consists of one or more thin screens embedded in transparent hydrogenous light guides, which also serve as a neutron moderator. The emitted particles interact with the scintillator screen and produce a high light output, which is collected by the light guides into a photomultiplier tube and produces a signal from which the neutrons are counted. Simultaneous gamma-ray detection is provided by replacing the light guide material with a plastic scintillator. The plastic scintillator serves as the gamma-ray detector, moderator and light guide. The neutrons and gamma -ray events are separated employing Pulse-Shape Discrimination (PSD). The detector can be used in several scanning configurations including portal, drive -through, drive -by, handheld and backpack, etc.

摘要： A gamma ray detector (50) comprises a plastic scintillation body (52) arranged to receive incident gamma rays to be detected. Photons are generated in response to the gamma rays by excitation and de-excitation processes in the scintillation body. The photons are detected using at least one photodetector (56) which generates an output signal representative of the energy of the gamma rays. The scintillation body has a detection surface to receive the gamma rays and a thickness in a direction substantially orthogonal to the detection surface that is not greater than 5 cm. Deconvolution techniques can be used to improve the output signal; the thinness of the scintillation body allows sufficiently accurate results to be obtained that individual isotopes can be readily identified. The detector can be usefully employed in portal radiation monitors.
