  • Gamma-radiation detector module for portal applications
    Patent number: 7274023
    Abstract: The gamma-radiation module includes a housing having a box-like container and a cover for hermetically sealing a pair of cylinders within the housing. Each cylinder includes scintillation material and a photomultiplier tube on a common cylindrical axis. The hermetically sealed module may be used singly or in multiple modules in portal applications whereby gamma-radiation from a source may be detected through a gamma-radiation transparent cover on the module.

  • Well logging apparatus with gadolinium optical interface
    Patent number: 6872937
    Abstract: A well logging apparatus includes a probe having a detector assembly. In an exemplary embodiment, the detector assembly includes a scintillator having scintillation a crystal capable of producing light when exposed to gamma rays, aphoto-multiplier, and an optical interface positioned between the scintillator and the photo-multiplier. The optical interface optically couples the scintillator and the photo-multiplier. The optical interface includes a gadolinium doped filter glass.
