Abstract
In a radiation detector, scintillation material flouoresces and the produced light is converted to electrical energy in an adjacent converter, separators are provided in spaces between the adjacent scintillators and converters. The separators may have a greater length than the adjacent scintillators, so that they will extend beyond to reduce cross-talk. The separators can extend toward the source of radiation for a height substantially greater than, and particularly five times, the height of the spaces between the adjacent scintillators to prevent X-ray scattering and function as a collimator. Optically opaque adhesive may be provided on the opposite ends of separators and pairs of scintillators and collimators, to prevent cross-talk.
